Answer: 20 degrees
Step-by-step explanation:
The given triangle is a right triangle. This means that the measure of one of the angles is 90 degrees. recall, the sum of the angles in a triangle is 180 degrees. Thus, the sum of the other two acute angles is
180 - 90 = 90
From the information given,
one acute angle = 70
other acute angle = 90 - 70
the measure of the other acute angle in the triangle is 20 degrees
