SO i have a problem that's "AB ll CD, Find x and y".(adsbygoogle = window.adsbygoogle || []).push({});

I got the answer of x=48, =144

Because first the measure they already gave you was 42. As well as y - 12for the other angle measure. And x was the measurement for D. blah it's too hard to explain but i got it correct.

My point is that in the next question i had no clue what to do. It was totally different but under the same category.

"In the figure, m<NML=120, PQ ll TU and KL ll NM. Find the measure of angle PRK."

How do i solve this?

Here's a visual
