Question

In the given figure alongside, angle ABC : angle BAC=2:3 and angle ACD=130^ find the value of angle ABC , angle BAC and angle ACB​

Answer 1

Let angle ABC, BAC AND ACB be = x,y and z

Step-by-step explanation:

Let the ratio be 2a and 3a.

2a+3a=130° (exterior angle=sum of two opposite interior angles)

5a=130°

a=26°

x=2a =2*26°=52°

y=3a=3*26°=78°

z+130°=180°(angles on a straight line)

z=180°-130°

z=50°
