Answer:
C, 68°
Step-by-step explanation:
Since all triangle have an interior angle measure of 180° and isosceles triangles have two congruent angles, all you need to do to find m∠f is to subtract 44° from 180° and then divide by two.
180°-44°=136°
136°/2=68°
It’s 3 points or more which lie in the same plane
