Question

what is the answer help me

Answer 1

The answer is 30

Explanation:

A triangle equals 180, so to find out the value X, first you need the other corner. You know that one side of that line is 100, and it is a straight angle. So the other side is 80. 80 + 70 = 150. To get 180, you need to add 30 to that 150, therefore the answer is 30.

Answer 2

B. 30°

Explanation:

By remote interior angle theorem:

100° = x + 70°

100° - 70° = x

30° = x

x = 30°
