Question

Find the measure of angle A.

A. 30
B. 45
C. 60

Answer 1

Answer:

It would be B, since right angles are 90 degrees, and all of the angles of a triangle have to add to equal 180 degrees. 180-90=90, 90÷2=45 degrees

Answer 2

B would be the answer b/c a triangle equals 180 degrees and u have one 90 degree angle so 180-90 = 90 so now u have two angles left , they are the same angle so 90/2=45
