In a right triangle, one of the angles is always 90 degrees, as it is a right angle.
Therefore, the three angles in a right triangle must add up to 180 degrees.
Given that one angle is 65 degrees, and the right angle is 90 degrees, we can calculate the third angle by subtracting the sum of the two known angles from 180 degrees:
Third angle = 180 degrees - (65 degrees + 90 degrees) = 180 degrees - 155 degrees = 25 degrees.
Therefore, the third angle in the right triangle is 25 degrees.
If a right triangle has an angle that is 65°, what is the third angle in the triangle?
