Sorry, slow connection. That means I will have slow responses. Give me a second :)

OpenStudy (volleyballlover55):

ok!

I have forgot my vocabulary when it comes to these lines so forgive me. :P

jabez177 (jabez177):

Line AB is supplementary because all lines are supplementary which means they add up to 180 degrees.

OpenStudy (volleyballlover55):

whats the answer for part A? :)

OpenStudy (volleyballlover55):

What is the measure of angle x? Show your work.

@jabez177 @sammixboo

jabez177 (jabez177):

Sorry. I'm thinking of a way to explain it. I haven't done these in ages.

OpenStudy (volleyballlover55):

ok..

jabez177 (jabez177):

Line AB and CD are parallel to each other. Angle R is 120 degrees so 65 degrees and x is congruent to angle R

jabez177 (jabez177):

Now on line AB, we have 65 degrees. Now if I remember correctly, we can subtract 65 from 120 to give us the missing angle x.

OpenStudy (volleyballlover55):

@sammixboo is that correct? :)

sammixboo (sammixboo):

APR and DRP are alternate interior angles, so the angles would equal the same. 120 and 120, so we need to subtract 120-65 to get x

OpenStudy (volleyballlover55):

so have we found the answer for A?

jabez177 (jabez177):

Yep! :)
