In a right triangle, one of the exterior angles measures 155°. What is the measure of the non-adjacent, non-right angle?
A. 55°
B. 65°
C. 75°
D. 85°

Respuesta :

We know, Supplementary angles equal to 180
So, adjacent angle + exterior angle = 180
adjacent angle = 180 - 155 = 25

Now, non-adjacent + adjacent = 90
non-adjacent = 90 - 25 = 65

In short, Your Answer would be Option B

Hope this helps!
