In a right triangle, one of the angles is always 90 degrees. The sum of the angles in any triangle is always 180 degrees.
Given that one angle is 90 degrees and another angle is 65 degrees, you can find the third angle by using the following formula:
\[ \text{Third angle} = 180^\circ - (\text{Angle 1} + \text{Angle 2}) \]
In this case:
\[ \text{Third angle} = 180^\circ - (90^\circ + 65^\circ) = 180^\circ - 155^\circ = 25^\circ \]
Therefore, the third angle in the triangle is 25 degrees.
