Classify the angle pair using all names that apply
Answer:
Vertical and supplementary
Step-by-step explanation:
Angles 1 and 2 are Vertically opposite angles and therefore they are equal to each other.
using angle A as the reference angle, what is the ratio of the opposite side to the adjacent side?
write the ratio as a fraction
Answer:
20/21
Step-by-step explanation:
Opposite / Adjacent = RT / AR
You have to find RT
Use the Pythagorean Theorem
AR^2 + TR^2 = AT^2
21^2 + TR^2 = 29^2
441 + TR^2 = 841 Subtract 441 from both sides
TR^2 = 841 - 441
TR^2 = 400
sqrt(TR^2) = sqrt(400)
TR = 20
Ratio: TR / AR = 20/29
find the area enclosed by the figure. Use 3.14 for π. (The figure is not to scale).
Answer:
97.27 yd²
Step-by-step explanation:
First let's find the area of the right triangle on the left side. To do that, multiply 6x5, then divide the product by 2, since a right triangle is half a rectangle.
6x5=30
30/2=15
Area of triangle=15 yd²
Find area of the middle rectangle. So multiply the length by the width.
9x6=54
Area of rectangle=54 yd²
Find area of the half circle. Formula for area of circle is [tex]A=\pi r^{2}[/tex]. Pi is about 3.14, and radius ([tex]r[/tex]) is 3. Radius is half of the diameter of circle, and the 6 on the left says the diameter of circle.
[tex]\pi[/tex]x[tex]3^{2}[/tex]≈28.27
Area of circle is about 28.27 yd²
Add up the three areas.
15+54+28.27=97.27

find the value of x please help I give brainly
20 points
Answer:
x=148
Step-by-step explanation:
First, find the missing angle by subtracting 100+48 from 180 (all of the angles in a triangle add up to 180). Then, subtract that from 180 (the angles are a linear pair, so they are supplementry, so they add up to 180) x+32=180.
x=148.

Answer:
A. 232 in²
B. 216 in²
Step-by-step explanation:
A. Box A is a cuboid/rectangular prism.
Surface area of box A = 2(LW + LH + WH)
L = 10 in
W = 2 in
H = 8 in
Surface area = 2(10*2 + 10*8 + 2*8)
= 2(20 + 80 + 16) = 2(116)
Surface area = 232 in²
B. Surface area of B = surface area of cube
Surface area of cube = 6s²
s = 6 in
Surface area = 6(6²)
= 6(36)
= 216 in²
NEED HELP ASAP PLEASE! BRAINLIEST TO RIGHT ANSWER! For two similar triangles ABC and DEF, the scale factor of ∆ABC to ∆DEF is 2 : 3. If AB = 2(BC) and DE = 3(BC), what is EF?
A. 6BC
B. 2BC
C. 3BC
D. 1.5BC
Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
pick the Quadrant that you would plot (4,2)
A. Quadrant III
B. Quadrant II
C.Quadrant IV
D.Quadrant I
Answer:
D.) Quadrant I
Step-by-step explanation:
The quadrants start from Quadrant I (in the top left) and continue counter-clockwise to Quadrant II, Quadrant III, and Quadrant IV
Quadrant I = (+,+)
Quadrant II = (-,+)
Quadrant III = (-,-)
Quadrant IV = (+,-)
Now in this case, (4,2) is positive in the x value, and positive in the y value - so it belongs in Quadrant I!

I need major help thank you
!NO LINKS, NO FILES!
please :)
Answer:
6
Step-by-step explanation:
Recall the area of a triangle formula
[tex]A=\frac{bh}{2}[/tex] where b = base and h = height
The triangle shown has a height of 4cm and a base length 3cm
Using this information we plug in the values into the formula
[tex]A=\frac{4*3}{2} \\4*3=12\\\frac{12}{2} =6[/tex]
Hence, the area of the triangle is 6 square centimeters
Answer:
Ok so the area of the triangle is 6
Step-by-step explanation:
a= 1/2 bh
a= 1/2 * 3 * 4
a= 1/2 * 12
a= 6
What is the simple interest rate for a $5,000 investment
that become $5,750 at the end of 2 years?
Answer: the answer is r=7.5%
Step-by-step explanation:
You get the formula A=P(1+nr) where A is the accumulated amount: 5750, P is the principal: 5000, n is the amount of years: 2, and r is the rate: unknown
Now you plug in what you know:
5750=5000(1+2r)
Divide 5000 on both sides
Decimal form: 1.15=1+2r
Subtract -1 on both sides
0.15=2r
And lastly divide by 2 on both sides
0.075=r
BUT WHEN FINDING THE RATE ALWAYS MAKE IT A PERCENTAGE
r=0.075*100=7.5%

Answer:
D
Step-by-step explanation:
If f(x) = 2x+3 and g(x) = x^2 + 1, find f(g(3)).
Answer:
23
Step-by-step explanation:
g(3) = 3²+1 = 10
f(g(3)) = 2(10) + 3
= 23
Let g(x)=3x−1 and f(x)=x2+1. Find (g◦f)(−5).
(g◦f)(−5)=nothing (Simplify your answer.)
Answer:
-384
Step-by-step explanation:
Solve for each function first.
g(-5) = 3(-5) - 1
g(-5) = -16
f(-5) = -5^2 + 1
f(-5) = -24
Multiply.
(fg)(-5) = (-16 x -24)
(fg)(-5) = -384
