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. A straight line is shown and is marked with three angles. The first angle measures 60 degrees. The second angle measures 60 degrees. The third angle is labeled y. The line between the 70 degree angle and angle y extends below the straight line. The angle formed is labeled angle x. Write and solve an equation to determine the measure of angle x.

Answer 1

50

Explanation:

According to this description, we'd have a 180 angle cut into three angles labeled 60, 70, and y. Therefore, we'd subtract the sum of 60 and 70 from 180. Since y and x are vertical angles, they are congruent.

70+60=130

180-130=50
