In right angle triangle, one of the angles = 90°
Let other two angles be A and B.
Sum of all the angles = 180°
⇒ A + B + 90° = 180°
⇒ A + B = 90°
From the question ⇒ A – B = 20°
Solving both equations gives A = 55° and B = 35°

In a right angle triangle, the sum of the other two angles apart from the right angle is always 90 degrees. So, if the difference between these two angles is 20 degrees, then one angle would be 45 degrees and the other angle would be 45 - 20 = 25 degrees.
