Question

A

22 degrees

b
3 degrees

c
40 degrees

d
20 degrees

Answer 1

the answer is d.

7x-1=4x+8

3x-1=8

3x=9
x=3

7(3)-1=20°

Answer 2

Bisects means it divides in two equal parts. So:

7x - 1 = 4x + 8
3x = 9
x = 3

This problem isn't over, though.

7(3) - 1
20

Because one of the parts equals 2, the whole thing equals double of that, or 40


Hope this helps!
