Question

Give me a right answer ​

Answer 1

Answer:

Given that

angle BAC = 70°

angle ACB = 50°

first we have to find angle ABC .

we know that the sum of all the angles of triangle is 180°

so,

70°+50°+x=180°

x+120°=180°

x=180°-120°

x=60°

now , we know that the sum of all the angles of a straight line is 180°

their for : x+60°=180°

x=180°-60°

x=120°

hence the angles ABD is 120°
