Answer:
38
Explanation:
Since for this kind of equation, it always has to equal 360 all around, but since we're only measuring the angle for one side, we have to get 180
So we have our work cut out for us with 155
So 180 - 155 = 25
So we have to find the x value that makes 25
32 - 13 = 19, so that answer is eliminated
38 - 13 = 25
So the answer is x = 38
