| To solve the problem, let’s compose and solve the equation. We apply the theorem on the sum of the angles of a triangle to compose the equation.
We start by considering the condition of the problem. It says that one of the acute corners of a right-angled triangle is 32 ° less than the other.
So, since the triangle is rectangular, one of its corners is 90 °.
Let’s denote by x ° one of the acute angles, then the degree measure of the second is (x – 32) °.
We get the equation:
x + (x – 32) + 90 = 180;
2x = 180 – 90 + 32;
2x = 122;
x = 61 °.
61 – 32 = 29 °.
Answer: 29 ° and 61 °.
