Answer 1

In a right triangle, one of the angles is always 90°. The sum of the angles in any triangle is 180°. If one angle is 90° and another is 65°, we can find the third angle by subtracting the sum of the known angles from 180°.

So we calculate the third angle as follows:

\[ \text{Third angle} = 180° - 90° - 65° = 25° \]

Therefore, the third angle in the triangle is 25°.
