Question

What is x? Options: 81, 57, 143, 66.

Answer 1

Answer:103 degrees

Explanation:

Straight line equals 180 degrees

180 degrees minus 77 degrees = 103 degrees

Answer 2

x = 103

Explanation:

In my opinion, because x and 77 are the supplementary angles, so 180-77 = x or x+77=180. The answer should be 103......even though it's not in the options (I'm sorry).
