Answer 1

Answer:

48 degrees

Step-by-step explanation:

First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.

Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.
