Find the measure of x(HEELP)

A.180

B.109

C.135

D.116

C.120

x = 109

Step-by-step explanation:

The exterior  angle of a triangle is equal to the sum of the opposite angles in the triangle

x = 45+64

x =109

 B. 109 degrees

Step-by-step explanation:

The two remote interior angles add up to the exterior angle which means if you add the two measures you will get x.

64 + 45 =     109    

rounding to the nearest thousandth would be 452,000
