Will give brainlest. how do i do this my notes aren’t making sense

Step-by-step explanation:

The question is

Find the measure of angle x

we know that

In this problem

----> by alternate interior angles

Because, each pair of these angles are inside the parallel lines, and on opposite sides of the transversal.

the solution is h=10 because you add 9 to each side of the equation.

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5
