Question

Look at the figure.
Based on the figure, which equation is true?

cos x° = 2 tan y°

tan x° = 2 sin y°

sin x° = 2 cos y°

sin x° = 2 tan y

Answer 1

@Data_LG2 i was wondering i you could help me with a few more and i'll be done with my assignment

Answer 2

Look at the bottom triangle,
look from the angle x

Answer 3

you can ask @eLg for this one..

Answer 4

identify the two sides given

Answer 5

@eLg can you help me please

Answer 6

give me a sec., I am solving it right now.

Answer 7

First step is to find the missing sides, AB and CD, which you do using the Pythagorean theorem.

Then find sinx, cosx, and tanx, and siny, cosy, and tany.

Answer 8

Explanation:
hypotenuse with x is equal to
\[hypotenuse = \sqrt{10^{2}+10^{2}}=10\sqrt{2}\]

Answer 9

adjacent side with y is equal to :
\[adjacent = \sqrt{10^{2}-5^{2}}=5\sqrt{3}\]

Answer 10

use SOH CAH TOA:
\[\sin \theta= \frac{ opposite }{ hypotenuse}\]
\[\cos \theta= \frac{ adjacent }{hypotenuse}\]
\[\tan \theta=\frac{ opposite }{ adjacent }\]

substitute the values,
My answer is \[tanx=2siny\]

Answer 11

@eLg thanks, your awesome!!

Answer 12

just let me review it

Answer 13

@brianjr227 thanks, your awesome too

Answer 14

Good answer @eLg but it'd be better to post the working/explanation before posting the answer... some people don't care about the working and will just see the answer and not bother trying to learn how to do it on their own.

Answer 15

@agent0smith oh ok. Next time I will do that. Is my answer right?

Answer 16

tanx=2siny looks right.

tanx=1, siny=0.5,

so 2siny = tanx = 1
