In a right triangle, one of the angles is always 90°. So if one angle is 65°, the third angle can be found by subtracting the sum of the other two angles (90° + 65°) from 180°, since the sum of all angles in a triangle is 180°.
Third angle = 180° - (90° + 65°) = 180° - 155° = 25°.
If a right triangle has an angle that is 65°, what is the third angle in the Triangle
