Question

The measures of two angles in this acute triangle are 78° and 35°.

What is the measure of the third angle?

Answer 1

First! we must remember that a triangle always equals 180°

If we have two angles then all we have to do is subtract.

180° - 78° - 35° = 67°

So your missing angle is 67°

Answer 2

67 because the total angle of a triangle is 180* so you add 78 and 35 and subtract 180 from your total
