Answer 2

Hello Friend ♥♥✌✌.

The ans:

Given, from fig, AC=AB and ACD=115

now,

ACD and ABC

are in linear pair.

therefore,

ACD+ABC=180 degrees

but, ACD is 115 degrees.

Therefore,

ABC+115=180

ABC= 65 degrees.

Now,

Given, AC=AB

therefore,

ABC=ACB=65 degrees.

Now, we know that

the sum of measures of all angles of triangle is 180 degrees.

therefore,

ACB+ABC+BAC=180

130+BAC=180

therefore,

BAC=50 degrees.

hope it helps you
