In a right triangle, one of the angles is always 90°. The sum of all angles in any triangle is 180°.
If one angle is 65° and another is 90°, we can find the third angle by using the formula:
\[
\text{Third angle} = 180° - \text{(first angle + second angle)}
\]
Substituting the values we have:
\[
\text{Third angle} = 180° - (65° + 90°) = 180° - 155° = 25°
\]
Therefore, the third angle in the triangle is **25°**.
