Find the measure of angle x. x = 150˚ x = 120˚ x = 145˚ x = 90˚

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle y

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the bottom triangle of the figure

solve for y

step 2

we know that

----> by vertical angles

we have

therefore
