One of the acute corners of the rectangle of the triangle is 36 Find its other acute angle.

To solve this problem, we introduce a conditional variable “X”, through which we denote the value of the second acute angle of a right-angled triangle.

Let’s take into account the fact that the sum of all the angles of a triangle is 180 degrees, and the right angle of a right triangle is 90 degrees.

Then, based on the data of the problem, we will compose the following equation: X = 180 – 90 – 36.

Solving this equation, we get X equal to 54 degrees.

Answer: The second acute angle of a right-angled triangle is 54 degrees.
