Question

Can someone find the value of x and show the steps pls​

Answer 1

x = 64°

Explanation:

Okay, so the 2x° and 128° are opposite ("alternate") interior angles

that means, with they're relationship, they are congruent (equal)

so....

2x = 128

/2 /2 (isolate variable)

x = 64°

Answer 2

x = 64

Explanation:

Because you know the two lines that are intersected by the transversal are parallel, you know 2x = 128 because they are congruent alternate interior angles.

So

2x = 128 Congruent Corresponding Angles Congruent Theorem

x = 64 Division property of equality (divide by 2)

Hope this helps! :)
