Answer:
x = 36.9°
Step-by-step explanation:
We need to find out what sides of the triangle we have, so we can find the formula for the missing angle, x.
We have been given the opposite and hypotenuse so we are using sine
SOH, CAH, TOA
sin (x) = opp ÷ hyp
Substitute in the values
sin (x) = 9 ÷ 15
Simplify
sin (x) = 0.6
Rearrange to find x
x = sin^-1(0.6) - Type this into your calculator
sin^-1 is the inverse or opposite of sinx = 36.8698... ≈ 36.9°

x=?

Answers
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] and tan60° = [tex]\sqrt{3}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
x [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
x = 4
and
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{2\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )
y [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 2
how to make h the subject in
m= r - h + 4d
Answers
9514 1404 393
Answer:
h = r +4d -m
Step-by-step explanation:
There are a couple of ways to go about this:
1) Solve it the way you would any 2-step linear equation.
Step 1:
Identify the terms that do not involve h on the side of the equation that has the h-term. Subtract those terms from both sides of the equation.
m -r -4d = -h
Step 2:
If the coefficient of h is not 1, divide both sides of the equation by that coefficient.
(m -r -4d)/(-1) = (-h)/(-1)
-m +r +4d = h
I like to have the leading coefficient be positive, so I might write this as ...
h = 4d +r -m
__
2) The only h term has a -1 coefficient, so it can be given a coefficient of +1 by adding h to both sides of the equation.
h +m = r +4d
There is an unwanted m term with the h term, so subtract that from both sides of the equation.
h = r +4d -m
Answer:
h = 4d -m + r
Step-by-step explanation:
m = r-h +4d
h = 4d -m + r
we know when the real root is r = h-4d
the m+h = r+4d is step 1
then simply h-m = 4d-m + r is step 2
then h = 4d -m + r

Please lemme know with explanation
Answers
Answer:
x = 60°, y = 100°, z = 120°, w = 80°
Step-by-step explanation:
x and 120° are adjacent angles on a straight line and sum to 180°
x + 120° = 180° ( subtract 120° from both sides )
x = 60°
Similarly
y + 80° = 180° ( subtract 80° from both sides )
y = 100°
and
z + 60° = 180° ( subtract 60° from both sides )
z = 120°
--------------------------------------------------------------------
The sum of the interior angles in a quadrilateral = 360°
sum the interior angles of the quadrilateral and equate to 360°
60° + 80° + 120° + 4th angle = 360°
260° + 4th angle = 360° ( subtract 260° from both sides )
4th angle = 100°
w and 100° are adjacent angles on a straight line and sum to 180° , so
w + 100° = 180° ( subtract 100° from both sides )
w = 80°

Tara can type 180 words in 4 minutes at this rate how many words can she type in 10 minutes
Answers
Answer:
450 words at a rate of 45 word per minute
Step-by-step explanation:
180 divided by 4 equals 45
times 10 equals 450
Answer:
450 words in 10 minutes
Step-by-step explanation:
To set this up you need to put it like this:
[tex]\frac{180}{4} =\frac{x}{10}[/tex]
From here, you need to cross multiply, which will get you to: 180(10) = 4x
Multiply 180 and 10: 1,800
The equation will now be: 1,800 = 4x
Now, divide both sides by 4: 450 = x

what is [70+(-30)]+[2+(-9)]+[0.3+(-0.1)]
Answers
Answer:
33.2
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.

Answer: 705 cm
Step-by-step explanation:
Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525
centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.
How high can Ron lift a feather with his magic?
Hermione = 3,525 cm
Hermione = 5 × Ron
Substitute Hermione = 3,525 cm into
Hermione = 5 × Ron
3,525 = 5 × Ron
Ron = 3,525 / 5
= 705
Ron = 705 cm

14) Using the same steps in 13, I found the factors. As the zeros are x=-6 and x=0, I got the factors (x) and (x+6). Then, I multiplied them and got x^2+6x, which is the answer.
15) x=1, x=1, x=2. These become the factors (x-1), (x-1), and (x-2). Then, by multiplying (x-1) and (x-1) you get x^2-2x+1. Multiply that by (x-2) to get your final answer, x^3-4x^2+5x-2.
16) Zeros are x=-1, x=5, and x=-2. You get the factors (x+1), (x-5), and (x+2). Multiply (x+1) and (x-5) to get x^2-4x-5. Multiply that by the other factor, (x+2), to get your final answer, x^3-2x^2-13x-10.

The width of a rectangle measures (26 – 8c) centimeters, and its length measures
(106 + 6c) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answers
Answer:
first one is correct
Step-by-step explanation:
length of a rectangle = 2b - 8c
breadth of a rectangle = 10b + 6c
now , formula to calculate the perimeter of rectangle is
p = 2 (l + w)
no substitute the value of l(length) and w(width)
p = 2{(2b - 8c) + (10b + 6c)}
p = 2(2b - 8c + 10b + 6c)
p = 2(12b - 2c)
p = 24b - 4c
