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>

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°
