Question

Two of the angles in a triangle measure 55° and 28°. What must be the measure of the third angle?

The measure of the third angle is

Answer 1

It must be 97 degrees

Answer 2

Answer: 97 degrees

Work Shown:

Let x be the third angle

For any triangle, the three angles always add to 180 degrees

x+55+28 = 180

x+83 = 180

x = 180-83

x = 97
