In any triangle, the sum of the angles is always 180 degrees. Since the triangle in question is a right triangle, one of its angles is already known to be 90 degrees.
We're also given that one of the non-right angles is 65 degrees. To find the third angle, we subtract the known angles from 180 degrees:
180 degrees - 90 degrees (right angle) - 65 degrees (given angle) = 25 degrees
Therefore, the third angle of the right triangle is 25 degrees.
If a right triangle has an angle that is 65degrees, what is the third angle in the triangle?
