Sum of the angles in a triangle = 180 degrees.

angle B + angle C = 90 degrees. (given)

So angle A = 180-90 = 90 degrees.

But angle A is thrice the angle B.

So angle B = 1/3 of angle A

= 1/3 * 90 = 30 degrees.

So angle C = 90-30 = 60 degrees. Because angle B + angle C = 90 degrees (given)

angle A = 90 degrees; angle B = 30 degrees; angle C = 60 degrees. Answer.
