Question

Please help!!! I understand x° but I am confused on how to come up with a value for y°. An explanation would great!!

Answer 1

50 degrees

Step-by-step explanation:

The sum of the degrees inside a triangle is 180 degrees. Since x is 40, the sum of the inner angles would be x + y + (x + y) which is 40 + y + 40 + y.

Set that equal to 180:

2y+80=180

2y=100

y=50
