CE and BD are angle bisectors of △ABC which intersect at point F. If ∠BFC=110°, find the measure of ∠A.
1 answer:
Answer:
∠A=40°
Step-by-step explanation:
Equation 1: ∠A+∠B+∠C=180°
Equation 2: ∠B/2+∠C/2+110°=180°
2(Equation 2): ∠B+∠C+220°=360°
∠B+∠C=140°
Equation 1 - 2(Equation 2): ∠A=40°
Therefore, ∠A=40°
