Question

I need some help quick:(

Answer 1

The answer is 20 degrees, because a straight line is equal to 180 degree, and when you add 90 degree to 70 degrees, you'll get 160 degree, and then, when you subtract 160 from 180, you'll get 20 degree

Hope this helps :)

Answer 2

The answer is C because that's is a 90 degree angle. So you just subtract 70 from 90.
