Question

What is the value of x?

Answer 1

In order to solve this problem, you must take a look at the figure. Since the left side and the right side are both equal to 21. This figure would be an Isosceles Triangle, meaning the two sides are equal. Therefore, you can conclude that x would be equal to the side opposite of it. So, to solve the problem you would do:

180 degrees - 38 degrees which equals 142 degrees.
But, 142 degrees would be the sum of the two missing angles, so you must divide that by two, which would get you the answer of each missing angle being 71 degrees, because the entire triangle must add up to be 180 degrees total.

Answer 2

your answer would be 76 degrees because the angles inside of a triangle is 180 degrees so since you have 38 degrees you must subtract 180-38 and you get 142 degrees which you must put in half so then you get 76 degrees
