Question

PLEASE HELP QUICK!!!!!!!! 30 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!In the figure below, angle Y and angle X from vertical angles. Angle Y forms A straight line with the 80° angle and the 60° angle.

Write and solve the Quetion to determine the measure of angle X.

Answer 1

x = 40°

Explanation:

Since y, 80 and 60 form a straight angle then their sum = 180°, hence

y + 80 + 60 = 180

y + 140 = 180 ( subtract 140 from both sides )

y = 40

x and y are vertical angles and thus congruent

x = y = 40°
