One of the corners of a right-angled triangle is 36 degrees. Find the rest of the corners of the triangle.

So, from the condition we know that the triangle that we are given is rectangular. That is, one of its angles is 90 °.

We also know that another angle is 36 °. It is necessary to find the third corner of the triangle.

Let’s start by recalling the triangle sum theorem. And she says that the sum of the angles of the triangle is 180 °.

It remains for us to subtract the sum of the known angles from 180 °:

180 ° – (90 ° + 36 °) = 180 ° – 126 ° = 54 ° third corner of the triangle.

Answer: 54 ° third angle.
