Answer:

The answer is 70, option B edge21

Step-by-step explanation:

This chicken nugget below me didn't read the full question.

"The vertex angle of an isosceles triangle measures 40°. What is the measure of A base angle?"

180-40 = 140 // the measure of the base angles combined

140/2 = 70 // divide by two to find the measure of A SINGLE base angle, like the question states.

Option B, 70
