    @peachpi I'm sorry I keep asking you. I'm just really bad at geometry and I'm trying ot get out of this class today. Thank you for helping me understand how to do it instead of giving me the answer also

    Well let's start off with this c: It doesn't exactly ask you to solve. We're just explaining how, if they gave you the values for x and y, we would be able to find the value of the hypotneuse. If they gave us 2 angle values, how would we find the third? Do you know?

    It's alright if you don't know, I just want to know if you do.

    Alright. We're given a 90 degree angle. If we were given x, we could do this All the angles in a triangle add up to 180 degrees So, we would subtract. 180 - 90= 90 90 - x = (the last angle) See where I'm coming from?

    The problem is not to find x & y, but to show how to use x and y to find the hypotneuse of this triangle.

    So, x is unidentified, we're using it as a variable. You know how all the angles in a triangle add up to 180, right?

    Eh it's ok. I put that down. My teacher knows I'm stupid at math anyway.

    Alright. It is a right triangle. That means one of the angles is 90 degrees. 180 - 90 = 90 If we subtract 90 from x (which is unidentified) we would get that last angle And sorry, but it isn't the pythagorean theorem. cx If once we got x, we would use the law of sines to find the length of the moon to the earth. To find this we set this up. \[\frac{ SinA }{ a }=\frac{ SinB }{ b }\]Let me redraw the triangle to find the right Sorry had to take a very important call :c
