Question

Fan and medal to anyone who can prove that their brain is skilled on geometry

Answer 1

?

Answer 2

Here you are given the hypotenuse of the triangle, the adjacent side (y), and the angle (30 degrees).

Which trig function relates adjacent side, hypotenuse and the angle?

Goal: Find y.

Answer 3

you dont have to yous trig

Answer 4

perhaps not, but would you please let @malehuman01 answer first?

Answer 5

sure

Answer 6

but there is an easier way without trig

Answer 7

I'd welcome you to demonstrate that easier method, but after malehuman01 and I finish.

Answer 8

im cool with that

Answer 9

Thanks.
@malehuman01 ?

Answer 10

is there any particular formula to solve for y?

Answer 11

Indeed there is: I was asking you which trig function involves the angle (30 degrees), the hypotenuse (4Sqrt(2)), and the adjacent side (y).

Have you learned the 6 basic trig functions yet?

sine
cosine
tangent
cotangent
secant
cosecant

??

Answer 12

sadly.. no

Answer 13

If not (seeing that you mentioned geometry), there are other ways to solve this problem, as our friend @svt2000 has mentioned.

Have you heard of "30-60-90 triangles"?

Answer 14

yes

Answer 15

not sure how to apply it though

Answer 16

Great. In that case I'd like to invite @svt2000 back into the picture, as I suspect that this 30-60-90 degree triangle approach is the one he had in mind. I'll keep an eye on this discussion and if necessary will step back in. Is that all right with you?

Answer 17

i would like to say that im a girl...

Answer 18

Yeah definitely, thank you!

Answer 19

oh okay xD

Answer 20

OK! I'm anxious to see how our friend svt2000 handles this. Hope she will guide you thru this step by step and let y ou come up with your own final answer.

Answer 21

ok so in a 30-60-90 triangle there are some special qualities..one of them is that the hypotenuse is 2x the length of the short side. and the longer side is square root of three times the shorter side. i drew a picture...
