In a right triangle, one angle is always 90°. The sum of the angles in any triangle is 180°. Therefore, the third angle can be calculated as follows:
- The right angle is 90°.
- The second angle is given as 65°.
- The sum of the angles is: \[ 90° + 65° + \text{third angle} = 180° \]
- To find the third angle, subtract the sum of the given angles from 180°: \[ \text{third angle} = 180° - (90° + 65°) = 180° - 155° = 25° \]
So, the third angle in the triangle is 25°.
