One of the sharp corners of a right-angled triangle is 3 times larger than the other. Find the sharp corners of the triangle.

the two acute angles in a right triangle add up to 90 degrees, so let’s take one for x and the other for 3x. Let’s get and solve the equation:
x + 3x = 90
4x = 90
x = 90/4
x = 22.5 degrees
the larger acute angle is 22.5 * 3 = 67.5
