Question

1. 8) x = x =

Explanation:

Step1: Identify angle - pair relationship in 7

The given angles are vertical angles. Vertical angles are equal.
$x = 62^{\circ}$

Step2: Identify angle - pair relationship in 8

The given angles are corresponding angles. Corresponding angles are equal when two parallel lines are cut by a transversal.
$x = 74^{\circ}$

Answer:

For 7: $x = 62^{\circ}$
For 8: $x = 74^{\circ}$
