In a right-angled triangle, one of the acute angles is 63 degrees.

In a right-angled triangle, one of the acute angles is 63 degrees. what percentage of the sum of the angles of the triangle is the other acute angle?

Let’s find what is the second acute angle of a given right-angled triangle:
90 – 63 = 27º

The angles of a triangle add up to 180º. We accept it as 100%. Let’s find what is equal to 1%:
180/100 = 1.8º.

Let’s calculate how many percent of 180º is the angle 27º:
27 / 1.8 = 15%.

Answer: An acute angle is 15% of the sum of all the angles of the triangle.
