Since you know the triangles are congruent/equal, you know that:
m∠A and m∠X are congruent and have the same angle, and so does:
m∠B and m∠Y
m∠C and m∠Z
A triangle is 180°. (the 3 angles have to add up to 180) To find m∠B, you can do this:
m∠A + m∠B + m∠C = 180°
21° + m∠B + 35° = 180° Subtract 21 and 35 on both sides
m∠B = 124° your answer is C
Equate the expressions for m.
7x = 3x + 20
4x = 20 . . . . . . . subtract 3x
x = 20/4 = 5 . . . divide by 4
The value of x is 5.
Answer:
151 in
Step-by-step explanation:
circumference = 2πr
where r = radius
given radius appears to be 24 so r = 24
so we have C = 2πr and r = 24 and we use 3.14 for π
So C = 2(3.14)(24)
==> multiply 2 and 3.14
C = 6.28(24)
==> multiply 6.28 and 24
C = 150.72
The closest answer is 151 so that is the answer
Answer:
40.5 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees, so to solve this all you need to do is add the two numbers you have and subtract them from 180.
62.5+77+x=180
139.5+x=180
-139.5 -139.5
x=40.5
