Direct Answer :
AB and CD are two parallel lines. PQ cuts AB and CD at E and F respectively. EL is the bisector of ∠FEB.

Full Appropriate Question :
AB and CD are two parallel lines. PQ cuts AB and CD at E and F respectively. EL is the bisector of ∠FEB. If ∠LEB =35°, then ∠CFQ will be :
A. 55°
B. 70°
C. 110°
D. 130°
Solution :
Given that,
AB ‖ CD and PQ cuts them
EL is bisector of ∠FEB
∠LEB = ∠FEL = 35°
∠FEB = ∠LEB + ∠FEL
→ 35° + 35°
→ 70°
∠FEB = ∠EFC = 70°ㅤ(Alternate angles)
∠EFC + ∠CFQ = 180°ㅤ(Linear pair)
70° + ∠CFQ = 180°
∠CFQ = 110°

Question: AB and CD are two parallel lines. PQ cuts AB and CD at E and F respectively the bisector of /_FEB. If /_LEB = 35° then /_CFQ will be
Answer:
/_CFQ = 110°
Step-by-step explanation:
Givne that AB and CD are two parallel lines. PQ cuts AB and CD at E and F respectively the bisector of /_FEB and /_LEB = 35°.
As EL is the bisector of /_FEB and /_LEB
So,
/_FEB = 2(/_LEB)
/_FEB = 2(35°)
/_FEB = 70°
AB || CD and /_FEB and /_DFE are consecutive interrior angles. So,
/_FEB + /_DFE = 180°
70° + /_DFE = 180°
/_DFE = 180°-70°
/_DFE = 110°
Now,
/_CFQ = /_DFE (vertically opposite angles)
So,
/_CFQ = 110°
