how the hell would i go about solving this problem. we're doing shit like this in physics and i have no idea what the hell i'm doing. befuddlement
just tell me how to find any of the sides because i'm too lazy to get my worksheet and look at the actual problem so this is just how i think it went and if you guys teach me i can work it on my own and actually learn how to do it instead of just copying
ps. last year they had me in an eighth grade math class and it was still considered "advanced" for my state just so you know how far i'm behind
I taught myself radians and stuff so I think I can at least handle that

X is the base's length.

Is that a 150 though? or 15 degrees?
If it's degress then that's trig you have on your hand.

Because if that was 150 I've have to be retarded not to know it.
notice how the o is high up and little

Degrees is
Angle A + Angle B + Angle C = 180 degrees
Thats not possible in this diagram because you're fucking stupid. Right angles are always 90 degrees.

I know, but that other guy solved it with 150.
And the 15 should be bottom right.

so the far angle is 15 degrees because there's like some invisible line forming a rectangle and that 15 degrees is in the upper left
meaning that top left angle is 75 degrees
i'm still confused because i need to know the length goddamnit

yeah, but there's no 15
15 degrees can go in either place since the 15 is external
Sin15 = x/75
x is the base.

I meant 15 degrees, and although I'm sure it's not drawn to scale, bottom right's angle seems to be 15 degrees.
what are you trying to do?
It looks like all of the angles are solved.
15+75+90=180
wait what the fuck are you trying to do anyway

15 goes in the opposite angle lol
I put 15 degrees up there because there's an imaginary line forming an imaginary triangle, so I should've put it in the right-side angle but didn't for some raisin

it's length i need

Is the 75 an angle or a length? No one knows what the hell you're talking about with such a shitty diagram.

no it was the external space because there was some imaginary right angle, but it's fixed now you twats
how do i find sine

You're not going to find the length with just the angles.
I'm too lazy to do the work but if the sides were 3, 3.5, and 5 they could also be 6, 7, and 10, or 12, 14, and 20. or 120, 140, and 200.
Angles alone don't give you the length.

Wait.
