This is trigonometry. How do I find x°? Not looking for the answer, just a guide. Can I bribe you with a brainliest?

Ok so if I think this is what your talking about then I hope this will help!
If not then I’m sorry..
So it’s kinda hard explaining it over text but it’s very helpful and important that you learn to label the sides!
(Opposite, adjacent, Hypotenuse)
Once you’ve got that concept down,
You can solve for x*
The longer leg of the right angle is always the Hypotenuse
The leg next to the angle
(weather the angle is givin or an X value)
Is always gonna be labeled A for Adjacent
The only leg left
(the leg across from the angle)
Is gonna be labeled opposite!
Then this is where the cos sin etc. come in!
All I’m saying is learn how to label the sides because it will make it easier to solve for X*
I would help you further into this but it’s way easier to understand if you watched a video on how to do trig.

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
