## Protractor Question

Hey Guys,

This question is confusing me a lot. It's telling me that those two angles are complementary so I have angle MNP + angle PNQ = 90

The answer in the back of the book is x = 143.

I can get 143 by adding 50 + 90 = 143 haha. But I've tried subtracting 92 - 53 and adding the answer to 92 and what not. It's just confusing me. Sounds simple but I don't know how to set this up.

## Re: Protractor Question

Ahhh, okay, okay. I get it. I see it now. I was getting so confused because of the image. You see, angle MNQ looks almost like a 90degree right angle judging from those black lines. I was so confused because of this.. I thought to myself, how can an almost 90 degree angle be a 143? I notice now that 143 IS m because the whole protractor is 180 degrees total. And m looks around the 143 mark.
