Question

Find the measure of angle x in the figure below:

Answer 1

x = 30°

Explanation:

see attached

Answer 2

30 degrees.

Explanation:

We are going to use two theorems: Triangle Sum Theorem and Vertical Angles Theorem. Please let me know if you need me to define them.

Here is how I solved this problem:

75+75 = 150.

180-150 = 30(Triangle Sum theorem)

x = 30(Vertical Angles theorem.)
