in triangle ABC,BC is produced to D.BF and FC arebisector of angle ABC and angle ACD respectively if angleBAC is equal to 70 degree and EF is equal EC and the measure of angle FEC is equal to
Answers
Answer:
not understood properly friend ok
Step-by-step explanation:
Given:The given triangle ABC, BC is produced to D. BF and FC are the bisectors of ABC and ACD respectively. If BAC 70° and EF = EC.
To find: Measure of FEC is equal to
Solution:
Let
Apply exterior angle property of triangle on ∆ABC
let us assume
Apply exterior angle property on ∆ FBC
now since triangle FEC is isosceles triangle, so angle ECF will also be r.
By angle sum property of triangle we can write
Hope it helps you.
