Question

What is the value of y?
Enter your answer in the box.

y=

Answer 1

Sum of the interior angles of the triangle= 180°

y+79°+37°=180°

y= 180° - 116°

y= 64°

Answer 2

64 degrees

Explanation:

The interior angles of a triangle must add up to 180 degrees. So, we can add up the other two, known angles to get 116. Subtract 116 from 180 (180-116) to get 64.
