Question

Triangle ABC is similar to triangle XYZ. Also, angle A measures 45° and angle C measures 60°.

What is the measure of angle Y?

_________ °

Answer 1

Assuming that angles X and Z are the same as A and C, the Y angle must be 75 degrees. It's because the sum of all three angles in any triangle give us 180 degrees, so:

180 - 45 - 60 =  75 degrees
