Question

In the figure shown, BEA = 100°. Point F is chosen inside DBEA so that line FA bisects EAB and line FB bisects EBA. The measure of BFA, is : (A)140° (B) 145° (C) 150° (D)155°

Answer 1

Answer:

140°

Step-by-step explanation:

In triangle BEA, angle EBA +angle EAB =80°(180°-100°)

Since BF and AF are bisectors so angle FBA +angle FAB =80/2=40°

Now in triangle BFA angle BFA = 180°-40°=140°
