Answer:

x = 20

Step-by-step explanation:

The picture shows that there is a right angle (this is indicated by the square in between the two straight lines)

every right angle has a total measure of 90 degrees

knowing this we can say: x + 70 = 90 or x = 90 - 70

either way, you would solve this to get x = 20
