Question

Two lines intersect at point B, which is also the endpoint of two rays.

What is the measure of angle ABC?

Answer 1

G

Explanation:

Angle B is a 90 degree angle. It is made up of two complementary angles ,57 and 3x. Using this equation

`57 + 3x = 90`

We solve for x

3x=33

x=11, then since plug in 11 into 2x and we get 22.
