Question

(05.02) PLEASE ACTUALLY ANSWER AND EXPLAIN WELL!! :)

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 80° angle and the 60° angle.

Write and solve an equation to determine the measure of angle x. (5 points)

Answer 1

• x = 40°

Explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

Then we have following equation to solve for x:

• x + 60° + 80° = 180°
• x + 140° = 180°
• x = 180° - 140°
• x = 40°
