Question

80

The measures of two angles of a triangle are 54° and 17°.
Find the measure of the third angle.

Answer 1

The measure of the third angle is 109°.

Step-by-step explanation:

The sum of all three angles in a triangle is always 180°.

To find the measure of the third angle, we can subtract the sum of the given angles from 180°:

180° - (54° + 17°) = 180° - 71° = 109°

Therefore, the measure of the third angle is 109°.
