Question

Use the figure below to answer questions 10-11.

10. Given that Segment XR and Segment EA are parallel, find the value of x.

11. What is the angle pair relationship called for the two marked angles?

Answer 1

The two marked angles are complementary angles. This means that the angles are equal.

Hence, X + 1 = 2X - 3.

By rearranging, X = 4.
