On a piece of paper, use a protractor to construct a triangle with angle measures of 50° and 70º.

What is the measure of the third angle?

The measure of the third angle is 60 degrees

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

Let

x ----> the measure of the third angle

so

solve for x

therefore

The measure of the third angle is 60 degrees
