Question

if one angle of a triangle is equal to the sum of the other two so that the triangle is a right angle

Answer 1

Sum of angles in a triangle is 180 degrees.

right angled triangle means one angle is 90 degrees

Therefore the other two angles together would measure 180-90=90 degrees

If smaller angle is a, the other is 2xa and the sum is a+2a = 3a = 90

Therefore a = 90/3= 30 degrees

the other angle is 2x30 = 60 degrees
