Question

(05.02) In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.

Write and solve an equation to determine the measure of angle x.

​

Answer 1

Explanation:

<y + 60 degrees + 70 degrees = 180 degrees (straight angles)

<y = 180 - 60 - 70

<y = 50 degrees and <x = 50 degrees (vertical angles)
