Let the measure of the third angle be x°.
According to the given information, the sum of the three angles is 180°.
Therefore, we can write the equation as:
x° + 54° + 26° = 180°
Combining like terms, we get:
x° + 80° = 180°
Subtracting 80° from both sides, we get:
x° = 100°
Therefore, the measure of the third angle is 100°. Answer: \boxed{100}.
The sum of the three angles in a triangle is 180°. If the measures of two of the angles is 54° and 26°, what is the measure of the third angle?
