Question

Solve for x. Picture will be in comments, explain how to get answer don't just give it too me.

Answer 1

Have you considered the sine or cosine?

Answer 2

I know that's how you're supposed to do it but I don't know how to use them.

Answer 3

Quote: "SOHCAHTOA"
The S, the C, and the T stand for -> Sin, cos, and tan, and it goes in order
Sine-> opposite/hypotenuse
Cosine-> Adjacent/Hypotenuse
Tangent-> Opposite / Adjacent

Answer 4

towards 28 degrees you have sine 28 degrees, and that is opposite/hypotenuse
You are given the opposite, (50) and need to find the hypotenuse (x)
So you just plug in sin 28 = 50/X

Answer 5

So I would use Sine? Because the side i have is the opposite and the one I need is the hypotenuse?

Answer 6

yes! u got it :)

Answer 7

Answer 8

Or the cosine. You have enough information to use either.

\(\sin(28º) = \cos(62º)\)

Answer 9

I'm not compleltey sure, but 106.502 is what I got

Answer 10

Did you try setting up the ratio and being sure?

\(\sin(28º) = \cos(62º) = \dfrac{50}{x}\)

Answer 11

I'm not sure how to do it

Answer 12

the sin(28)= 0.469 and so does cos(62)

Answer 13

You will need a calculator to calculate the sine or the cosine.

Answer 14

Well, there you go. Add that to the ratio equation and solve for x.

Answer 15

It had better not say either of those. You should start with 50/x, not with x/50.

Also, whoever requires you to "swap sides" like that needs to take a chill pill. No one should care about something like that.
