Answer:

The measure of the third angle is 100°

Step-by-step explanation:

<em>The sum of a triangle is 180 degrees. If the measures of two of the angles is 54 degrees and 26 degrees, what is the measure of the third angle?</em>

<em />

To solve this, we simply need to remember that the sum of angles in a triangle is 180 °

Let x be the measure of the third angle

26 ° + 54° + x = 180°

80 ° + x = 180°

Subtract 80 from both-side of the equation

80° - 80° + x = 180° - 80°

x = 100°

Therefore the measure of the third angle is 100°
