It asks to find Q, the right answer is 66, but I don't know how to obtain it.

9/11
What a troll

Q + 76 + 38 = 180

but what justifies that?

No, no, like the angle theorem.

|dw:1443733937696:dw|

Yes, I understand, but it is asking me to find Q. And, I don't know why you are using 38.

|dw:1443733999374:dw|

we need to find R first to find Q

there's a third angle (let's call it X) that you need to find first

to use the 180 rule, you need a straight line

Right, that is where I get lost, because I don't know what to do after that.

|dw:1443734371106:dw|

X = 38, using the corresponding angle rule|dw:1443734459130:dw|

Oh okay, that would be because they are same side angles? I'm sorry xd I know I ask a lot

yes, same side angles
