One of the acute angles in a right triangle has a measure of 36.6°. What is the measure of the other acute angle?
Solnce55 [7]
Triangles equal 180 degrees total
It’s a right triangle so one of the angles is 90 degrees and we know another angle is 36.6
So 90+36.6= 126.6
180-126.6= 53.4
So I’m assuming the correct answer is C since that’s the closet number to 53.4
