Question

Three angles of a triangle have measures of 63.5°, 76.5°, and 2x°. Ariette, Bertrand, and Carly each wrote an equation describing the relationship among the three angles. Touch the student who wrote the correct equation.

Answer 1

Either 63.5 + 76.5 + 2x = 180 or some variation of it.

Explanation:

The sum of all the angles in a triangle equals 180 so any answer would have to add up the three angles given and set them equal to 180.

Answer 2

The three angles of a triangle must add up to 180°, so the correct equation is:
63.5° + 76.5° + 2x° = 180
