Aright triangle, one exterior angle is 155°, what is measure of non adjacent, non right angle?

65

Step-by-step explanation:

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

So 65 degrees is your answer.
