Answer:
the correct answer is 80 degree
which is not in the option.....
( you can write 70 degree bcoz it is nearest to the 80 degree....)
Step-by-step explanation:
a + b + 130 = 180
a + b = 180-130
a + b = 50
a = 20
b = 30
40 + 60 + x = 180
x = 180 - 100
x = 80 degree....
hope it helps you.....☺☺☺
