Question

2. A triangle has two angles measuring 44 and 47. Determine the measure of the third angle.

Answer 1

44+47=91
180-91=89
so the measure of the 3rd angle is 89

Answer 2

Answer: M{x°}=89

A triangle has 3 sides, and the total degree is 180°. So make a equation to find the third degree (x).
