Question

Find the measure of the third angle of a triangle given that the first two angles are 44o and 72 o. Show your work.

Answer 1

Answer: The measure of the third angle of a triangle is 64°.

Explanation:

Since we have given that

First angle = 44°

Second angle = 72°

Let the third angle be x.

As we know that the sum of all three angles of a triangle is supplementary.

`44^\circ+72^\circ+x=180^\circ\\\\116^\circ+x=180^\circ\\\\x=180^\circ-116^\circ\\\\x=64^\circ`

Hence, the measure of the third angle of a triangle is 64°.
