The acute angles of a right triangle are 24:21. Find these angles.

The solution of the problem:
1. Let’s define what is the sum of two acute angles of a right-angled triangle.
180-90 = 90 degrees.
2. What is the sum of the two numbers in relation to the acute angles of the triangle.
24 + 21 = 45.
3. How many degrees are there in one part?
90/45 = 2 degrees.
4. Find out what is equal to one acute angle of the triangle.
2 * 24 = 48 degrees.
5. What is the other acute angle?
2 * 21 = 42 degrees.
Answer: One acute angle of a right-angled triangle is forty-eight degrees, the other angle of a triangle is forty-two degrees.
