Question

One angle of a right triangle measures 70°. What is the measure of the other acute angle?

Answer 1

20 degrees

Explanation:

Since all three angles of a triangle have to add up to 180 degrees and we know two of the angles, 90 degrees and 70 degrees

90 + 70 = 160

180 - 160 = 20

Answer 2

All angles in a triangle add up to 180 degrees, so if you have a right triangle, one angle is 90 and the other is 70, so add 90+70= 160

Then 180-160=20

Your answer would be 20.
