Question

The measures of two angles of a triangle are 37° and 25°. What is the measure, indegrees, of the third angle?

Answer 1

You can determine the measure of the third angle using the fact that the interior angles of a triangle add up to 180°.

Using the above fact, you can set the following equation:

`37^(\circ)+25^(\circ)+x=180^(\circ).`

Where x is the measure of the third angle.

Solving for x, you get:

`x=180^(\circ)-37^(\circ)-25^(\circ).`

Therefore:

`x=118^(\circ).`

Answer:

`118^(\circ).`
