Answer :
The measure of each base angle is 56°.
Step-by-step explanation:
- The isosceles triangle has two base angles that are congruent (same measure).
- Let the measure of each base angle is 'x'.
- The sum of angles in a triangle add to 180°.
base angle + base angle + 68° = 180°
2x + 68° = 180°
2x = 112°
x = 112/2
x = 56°
Therefore, the measure of each base angle is 56°.
