A triangle has angles measuring 15° and 45°. What is the measurement of the triangle’s third angle?

nexus9112 [7]

First you need to know that the internal angles of a triangle always equals 180°. Therefore:

15+45= 90°

Then since the angles should equal 180, you do:

180-90=90

So the missing angle equals 90°
