Question

Given in the figure below, find the values of X and Z.

Answer 1

Explanation:

8x-12+104=180°

= 8x=180-92

= x=88/8

= x=11°

104=y

Answer 2

Explanation:

Angles (8x - 12) and 104 are "straight angles;" their sum is 180 degrees.

Therefore, 8x - 12 + 104 = 180, or 8x - 12 = 76, or 8x = 88.

Dividing both sides by 8, we get x = 11

Angles z and 104 are vertical angles and are thus equal to one another. Thus, z = 104 degrees
