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

Q + 76 + 38 = 180

but what justifies that?

No, no, like the angle theorem.

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

we need to find R first to find Q

Yes, but R=76 and Q is right next to it, so why is the answer 66, if even when I take it from 180, it does not give me that.

|dw:1443734245275:dw| there's a third angle (let's call it X) that you need to find first
Vocaloid
  • Vocaloid
to use the 180 rule, you need a straight line
Vocaloid
  • Vocaloid
Q + R does NOT equal 180, since Q and R don't make a straight line when you put them together|dw:1443734334124:dw|

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

notice how Q, R, and X (the third angle) make a straight line? we need to find x, and that's why we need 38
Vocaloid
  • Vocaloid
X = 38, using the corresponding angle rule|dw:1443734459130:dw|
