Question

A road sign in the shape of a triangle has two interior angles that have the same measure as shown.

What is the measure of the third interior angle?

Answer 1

Answer: A: 120

Explanation:

When adding all sides of a triangle it should always equal 180 degrees so by adding 30+30=60 after you do 180-60=120 or the proper way is 30+30+x=180

60+x=180

-60 -60

x=120
