Answer:
39
Step-by-step explanation:
In figure A and B the degree of A is 10 and B is 20.The sum of these degrees is 30 and as we know the total degree of a triangle is 180 degree so we lets that degre is equal to 150.
If that degree is 150 than x is equal to 30 because the sum of interior and exterior is 180 degree
