Question

What is they answer for this question

Answer 1

x = 8

Explanation:

When two parallel lines are cut by a transversal, alternate interior angles are congruent. These two angles are equal to each other, so we can form an equation.

10x + 2 = 11x - 6

Now, work backwards to find x.

10x + 8 = 11x

8 = x

Answer 2

C

Explanation:

11x - 6 and 10x + 2 are alternate interior angles and are congruent , then

11x - 6 = 10x + 2 ( subtract 10x from both sides )

x - 6 = 2 ( add 6 to both sides )

x = 8
