Question

Two of the angles in a triangle measure 7° and 161°. What is the measure of the third angle?

Answer 1

first, you should know that there are 180 degrees in a triangle. what you will do is:

180-161-7=12

the measure of the third angle is 12

Answer 2

161+7=168 180-168=12. answer:12

Explanation:

all triangles add up to 180, so if you add 7 and 161 together, the last angle has to make it so that it equals 180. therefore, it would be 12.
