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

Plug in

Subtract 90 from both sides

Combine like terms.

So this shows that the sum of the other two angles is 90 degrees.
