Question

answer the 7th question for brainlist

Answer 1

Answer:

45

BCD=FCG=60 (VOA)

BCA+BCD+DCE=180 (LINEAR PAIR)

BCA=180-60-75=45

BAC=BCA=45 (BA=BC)

Cheers!

Answer 2

Answer:

A). 45°

Step-by-step explanation:

∠BCD=60° ( Reason : Vertically Opposite Angle with ∠FCG )

∠BCE= ∠DCE+∠BCD=75° +60°=135°

∠BCA=180°-135°  ( Angles on a straight line is 180°)

Given △ABC is isosceles with AB=BC.

Hence,

∠BAC=∠BCA (Base angles of Isosceles  △)

Hence,

∠BAC=180°-135°=45° (ANS)
