1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle. A. Equilateral
B. Scalene
C. Isosceles

Its Isosceles

cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles

Isosceles

Step-by-step explanation:

An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.
