Answer:
tan r = 35/12
Step-by-step explanation:
you use the rule tan=opposite/adjacent
The required ratio equivalent to tan(R) for triangle RTS is 35 / 12.
A triangle RTS is given with perpendicular = 35 base = 12 and the hypotenuse = 37
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
In order to find out the ratio equivalent to tan(R).0
We know that,
tan(r) = perpendicular / base
from given,
tan (R) = 35 / 12
Thus, the required ratio equivalent to tan(R) for triangle RTS is 35 / 12.

What does likelihood mean in math
Likelihood is the probable chances of occurrence of an event.
It simply means: what’s the chance “x” will occur?

The coordinates of the endpoints of EF are E( – 9,11) and F(1,6). Point G is on EF and divides it such that EG:FG is 2:3. What are the coordinates of G? Write your answers as integers or decimals.
Answer:
(-3,8)
Step-by-step explanation:
Given the coordinates of the endpoints of EF are E( – 9,11) and F(1,6). Point G is on EF and divides it such that EG:FG is 2:3.
Coordinate of G is expressed as shown;
X = ax1+bx2/a+b
X = -9(2)+3(1)/2+3
X = -18+3/5
X = -15/5
X = -3
Similarly;
Y = ay1+by2/a+b
Y = 2(11)+6(3)/2+3
Y = 22+18/5
Y = 40/5
Y = 8
Hence the coordinate of point G is at (-3,8)

Find the unknown angles from
the given figure.
(2x-3)°
(2x-43)
Answer:
2x-3 = 29
8x = 128
x+7 = 23
Step-by-step explanation:
The sum of the angles of a triangle is 180
2x-3 + 8x+ x+7 = 180
Combine like terms
11x+4 = 180
Subtract 4 from each side
11x+4-4= 180-4
11x = 176
Divide by 11
11x/11 =176/11
x =16
2x-3 = 2*16-3 =32-3 = 29
8x = 8*16 =128
x+7 = 16+7 = 23

- Use the numbers 2,165 and 4,428 to write and solve an equation that uses borrowing (regrouping).
Answer:
4,428-2,165=2,263
Step-by-step explanation:
you regroup the 2
The equation that uses numbers 2,165 and 4,428, and can be used to write and solve an equation that uses borrowing is 4,428-2,165=2,263.
What is Borrowing?Borrowing in subtraction, like "carrying" in addition, means to take quantities from one number and assign them to the next. The 10 is borrowed from the next higher digit column in this approach to generate a positive difference in the next column.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='. An equation that uses borrowing or regrouping can be written as,
4,428 - 2,165 = 2,263
Hence, the equation that uses numbers 2,165 and 4,428, and can be used to write and solve an equation that uses borrowing is 4,428-2,165=2,263.

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have:
The vector is (-3, 5)
The reflection line is y = x
The transformation rule:
(x, y) → (y, x)
(-3, 5) → (5, -3)
Thus, the reflection vector is (5, -3) after reflecting over line y = x the answer is (5, -3).

Please help ASAP IM IN DESPREATE NEED OF HELP
EVEN IF YOU COULD HELP WITH ONE I'D BE HAPPY I JUST DON'T UNDERSTAND WHAT THEY ARE ASKING.
Answer:
See the attached image for the graph of the first system.
Step-by-step explanation:
Here's how to graph the first system.
Start with the inequality [tex]-y \le -2x-3[/tex]. You can make this easier to work with by multiplying through by -1. Remember to switch the inequality sign when multiplying by a negative number. OK, you get the inequality
[tex]y \ge 2x+3[/tex].
The graph will be a half-plane -- all the points on one side of a line. The line that is the boundary of the half-plane has an equation: [tex]y=2x+3[/tex] -- just use an = sign instead of the inequality sign.
Graph the line.
The equation of the line is in slope-intercept form: y = mx + b, so you can tell the y-intercept is 3 and the slope is 2 (think of it as a fraction 2/1). Graph the line by going to the point (0, 3) -- the y-intercept -- then use the slope 2/1 interpreted as "rise over run" to go up 2 units and right 1 unit, arriving at the point (1, 5). Draw the line through those points, (0, 3) and (1, 5).
Now you have to decide which side of the line the inequality [tex]y \ge 2x+3[/tex] is describing. To do this, pick a point which is not on the line, plug its coordinates into the inequality; if the result is true, shade the side of the line the point you picked is on (if false, shade the other side!)
An easy point to pick in this case is the origin, (0, 0). Put zeros in for x and y in the inequality, and you'll get the statement [tex]0 \ge 2(0)+3 \, \Rightarrow \, 0 \ge 3[/tex]. That's false, so shade the side of the line not containing the origin. In the image below, the shading is in purple.
All right, now for the other inequality, [tex]x+2\le 0[/tex]. Subtract 2 from both sides and the inequality becomes [tex]x \le -2[/tex]. This, too, graphs as a half-plane whose boundary line has equation [tex]x=-2[/tex]. Graph the line. A line with an equation that has x in it but not y is a vertical line with all its x-coordinates equal to the number on the right side of the equation. This line is vertical and goes through points such as (-2, 0).
Pick a point not on the line (the origin works again). Put the coordinates into the inequality to get [tex]0\le -2[/tex] which is false. Shade the side of the vertical line which does not contain the origin. In the image below, the shading is in black.
Finally, YAY! \o/ , the solutions to the system are all the points in the plane that got shaded twice. In the image, they are the cross-hatched points above the purple line and to left of the black line.
Note: If you get a system with three inequalities, you'll be graphing three half-planes and looking for points that got shaded three times!
Note: One of your questions has the inequalities [tex]x \ge 0[/tex] and [tex]y \ge 0[/tex] in it. These two inequalities say that the x and y coordinates are both positive or zero, confining your attention to Quadrant I in the upper-right part of a graph, above the x-axis and to the right of the y-axis.

is the sum of the other
three angles?
A parallelogram is a quadrilateral. Therefore, the sum of its interior angles is 360 degrees.
If we know that one angle is 37 degrees, then the sum of the other three angles is: x + 37 = 360
The sum of the other three angles = 323 degrees

How are the shapes alike ?
Answer:
those 4 options are wrong, unless I am d.u.m.b
Step-by-step explanation:
both of those figures have 6 faces, and 8 edges.
Have a nice day! :-)
Answer:
Each shape has 12 edges
Step-by-step explanation:
Every cube (regular hexahedron) has 6 square faces and each face has 4 edges. However, each edge is shared between 2 faces. So, you can determine how many edges there are by multiplying 6 x 4 and dividing the resulting number (24) by 2, getting the final number of 12.
