Hi lovely /Sci/
Would you be so kind to help me out here?

I appreciate it so much, thank you!

Should have payed attention in geometry.

Not doing your homework

gtfo

I have ALWAYS been doing my homework. The thing is, that they introduce geometry in Danish schools very late compared to USA. I am having math a B level in college (1. year), which is pretty good actually.

If you could help me out here, I might get a chance of understanding how to to it.

You have enough information there to be able to construct the dimensions of triangle ADE, from there you can use that data to find triangle BCE's dimensions and the rest is just Pythagorean theorem.

I think.

Fuck, I'm rusty on my geometry. Saging because it's a homework thread but I'll see if I can't assist.

find Euclid's Elements free online and read it. Then rip your teacher a new asshole.

done.
there is probably a faster way to do part 3... i used pythagoras (a^2 + b^2 = c^2)
...but i get the correct answer anyway.

have a nice day OP.

oh good.
apart from pythagoras, i just used angles in a triangle must add up to 180 degrees...and the SIN rule...which i think you know.
(in same triangle SINA/a = SINB/b = SINC/c ... where each letter is an angle and its corresponding opposite side)

..keep in mind that this is really simple in right angled triangles because SIN(90) = 1...so you can just ignore it completely (like i did in the last step)
neat, huh?

Very need, sir.
I love you :-D
