Answer:
132
Step-by-step explanation:
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
x = 60° + 72°
x = 132°
x=132
Hey There!
The angle that is equal to 48 and angle x are supplementary angles meaning that they will add up to equal 180
so to find x we subtract 48 from 180
180-48=132
therefore x=132
