Answer:
x = 41 degrees and y = 98 degrees
Explanation:
The diagram shows that the two sides are the same, which means their angles are too. The angle we were given, 42 degrees, due to the two little markings on its side and variable x's side, means that the two are equal. So x = 41 degrees.
All triangles have angle total of 180 degrees, since we already know two of them (Angles), our third has to be what is remaining of the 180 degrees.
180 = 41 + 41 + y
180 = 82 + y
So we move 82 to the other side, making it a subtraction equation..
180 - 82 = y
98 = y
Answer: x = 41 degrees and y = 98 degrees
