Question

A puppeteer is making a triangular hat for a puppet. If two of the three angles of

the hat both measure 30 degrees. What is the measure of the third angle?

Answer 1

The triangle is an isosceles triangle and the measure of the third angle is 120°

Explanation:

the other nd 2 angles in the triangle both measures 30 degrees, the triangle angle sum theorem states that all the angles in a triangle add up to 180 degrees. Add the first two angles together and subtract it from 180. That's

180 - 60 and it equals 120
