hello
A.
the kind of angle pairs formed by both angles is called an alternating angle
B.
both angles are equal. i.e 2x + 24 = 3x
C. to solve this, let's solve for x first
x is equal to 24
x = 24
3x = 3 * 24 = 72
D. 3x = 3(24) = 72
2x + 24 = 2(24) + 24 = 48 + 24 = 72
the angles both measure 72 degrees
