Question

Two of the angles in a triangle measure 154° and 20°. What is the measure of the third angle?

Answer 1

Answer:

6°

Step-by-step explanation:

The angles in a triangle always add up to 180°. Let’s call the third angle x. That means that:

154 + 20 + x = 180 ->

174 + x = 180 ->

x = 180 - 174 ->

x = 6°
