Question

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

X =50 Y is also 50 since they are vertical angles

Explanation:

70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )

130 +X =180

X = 180-130

X=50
