Question

Find the values of x and y for which the lines are parallel.

A. x = 78, y = 53
B. x = 53, y = 78
C. x = 40, y = 53
D. x = 78, y = 55

Answer 1

Will medal need help!

Answer 2

If 2 parallel lines are cut by a transversal, alternate interior angles are congruent. That is why the two angles are marked 40. See attached diagram.

Answer 3

The sum of the interior angles of a triangle is 180.

y + 10 + 40 + 77 = 180 @jadesterxx Solve for y. Post what you get, okay?

Answer 4

If you find y, we can quickly get x, and knock out this problem.

Answer 5

I got y= 53?

Answer 6

That is what I got. Now, for x.

Answer 7

63 + 40 + x - 1 = 180

Answer 8

@jadesterxx x = ?

Answer 9

So would x = 78?

Answer 10

That is what I got.

Answer 11

Thank you a lot!

Answer 12

Be careful with the options. The correct answers are reversed in one of them.
