Question

in adjacent figure if given that ab=ac angle bac =36 degree angle bda=45degree and angle aec=40 degree find angle abc angle acb angle dab angle eac
​

Answer 1

Answer:

Step-by-step explanation:In △ABC

AB=AC

So △ABC is isoceles.

⇒∠ABC=∠ACB

∠BAC+∠ABC+∠ACB=180  

∘

 (Angle sum property of triangle)

36  

∘

+∠ACB+∠ACB=180  

∘

 

2∠ACB=180  

∘

−36  

∘

 

2∠ACB=144  

∘

 

∠ACB=

144
