Help!!

A pair of parallel lines is cut by a transversal:

A pair of parallel lines cut by a transversal is shown. The inside bottom right angle is labeled 80 degrees. The alternate interior angle is cut by a ray and is labeled as x on one side and 20 degrees on the other.

What is the measure of angle x?

60 degrees
70 degrees
80 degrees
100 degrees

Answer 1

so the entire left upper (alt int) is going to be 80, from the bottom. so you just take 20 from 80 to find x

Answer 2

Is it 60?

Answer 3

yep

Answer 4

Thnx, If I get it right I'll tell you!

Answer 5

Oh, Can you help with another one?

Answer 6

sure

Answer 7

KK, Thx

Answer 8

A pair of parallel lines is cut by a transversal, as shown:

A pair of parallel lines is shown cut by a transversal. Angle x is located in the upper right exterior next to the transversal, and angle y is located in the bottom left exterior corner of the transversal.

Which of the following best represents the relationship between angles x and y?

x = 180 degrees − y
y = 180 degrees − x
x = y
x = 2y

Answer 9

those are alternate exterior, do you know the rule for alternate exeterior?

Answer 10

What rule?

Answer 11

any time you have alternate exterior (or alternate interior) the angles are equal

Answer 12

Okay

Answer 13

But that's not one of the choices

Answer 14

there is not a choice where they are equal?

Answer 15

x = 180 degrees − y
y = 180 degrees − x
x = y
x = 2y

Answer 16

that is ok

Answer 17

So is it B?

Answer 18

no, b is no just equal, which one is just x equals y?

Answer 19

Oh, C!

Answer 20

there you go
