Question

please give me answer​

Answer 1

Answer:

Step-by-step explanation:

Using exterior angle property of triangle,

∠BAC + ∠ACB = 110°       ----- 1

Also as AB=AC

∠ABC = ∠ ACB

Now, Using angle sum property of triangle,

∠ABC + ∠ACB + ∠BAC = 180°

∠ABC + 110° = 180°        (From 1)

∠ABC = 70°

So, ∠ACB  = 70°

∠BAC = 40°

Now , Using Exterior angle property of triangle,

∠BCD = ∠ABC + ∠BAC

∠BCD = 110°
