Well, you could use the following property: the sum of the three angles of any triangle is 180 degrees.
So let x, y, and z be the three angles of a triangle
According to the given property, this means that
Since " one angle of a triangle is 90 degrees", this means that we'll let
Start with the given equation
Subtract 90 from both sides
Combine like terms.
So this shows that the sum of the other two angles is 90 degrees.
