Question

in the given figure find the value of x​

Answer 1

Answer:

BCD is a straight line

180-110

70

Answer 2

Answer:

x=40°

Step-by-step explanation:

ACD+ACB=180°(linear pair)

110°+ACB=180°

ACB=70°

In triangle ABC,

AB=AC

therefore angle ACB=angle ABC

ACB=ABC=70°

Now,ACB+ABC+BAC=180°(angle sum property)

70°+70°+BAC=180°

BAC=180°-140°

BAC=40°
