Question

Two angles in a triangle have measures of 28 and 51

what is the measure of the third angle?
A. 101
B. 23
C.281
D. 79

Answer 1

A

Explanation:

the sum of the angles of a triangle is 180 degrees, so in order to find the third angle, we have to subtract two other given angles from 180°:

180° - 28° - 51° = 101°
