I need help with this

x=32

Step-by-step explanation:

The angles in a triangle add up to 180 degrees.

Since we know a=10 the other two angles must add up to 170 degrees.

We can now solve for x

We can sub in x to both angles to see if they angles add up to 180

the difference between a number and 5 is -2.

step-by-step explanation:
