Write the given of the sentence if one angle of a triangle is 90 degrees ,then the other two add to 90 degrees?

For this case we have that the sum of the angles of a triangle is equal to 180 degrees.

We have then:

Where,

x, y, z: angles of the triangle

If one of the angles is equal to 90 degrees, we have:

Clearing we have:

if z = 90 then,

chicken chicken chicken
