In a right triangle, one angle is always 90°. The sum of the angles in any triangle is 180°.
If one angle is 65° and the right angle is 90°, we can find the third angle as follows:
\[ \text{Third angle} = 180° - (65° + 90°) \]
Calculating that:
\[ \text{Third angle} = 180° - 155° = 25° \]
Therefore, the third angle in the triangle is 25°.
