Question

10. What is the value of x?
105°
148°
x

Answer 1

Explanation:

The supplement of 105 = 180 - 105 = 75

The supplement of 148 = 180 -148 = 32

x is the sum of these two angles

x = 32 + 75

x = 107

Exterior angles are the sum of the 2 angles not connect to the exterior angle you are trying to find.
