Question

What is the value of y?

Enter your answer in the box.

Answer 1

y= 64°

79°+37°+?°=180° so you do it backwards.....
180°-79°-37°=64°

Hope this helps :)

Answer 2

When dealing with the angles of triangles, they are always going to equal 180 degrees.
So, 79 + 37 + x = 180
116 + x = 180
-116 -116
-------------------
x = 64 degrees

To check that you can just add them all together and see if you get 180.
64 + 79 + 37 = 180
