How do you solve this?

At some point I got 3x sqrt74/5= 7/sqrt 74

i am confused because you have 3 variables, A, C and x. what are you trying to solve?

I am solving for this :tan∠A - csc∠C = 3x

here are the variables

tangent A= 7/sqrt 74 and csc C= sqrt74/5

Hello?

idk what you are saying

Its tangent a subtracted from cosecant C and those are the values of them

What the bannana are you talking about?

haha

jonh—please be respectful.

Yes that is right

Ok, so you really have:
\[\frac{7}{\sqrt{74}} - \frac{\sqrt{74}}{5} = 3x\]

Yes exactly

First things first, I would do the subtraction on the left. Do you know how to do that?

do you subtract the square?

So, 3x = -39/(5*SQRT(74))
=> x = -13/(5*SQRT(74))

did you use the values GT?

I am kind of shaky on how to subtract with squares shadowfield

|dw:1326987711543:dw|

|dw:1326987783481:dw|

is that the simplified answer? Because I don't see it on my answer choices?

|dw:1326988065164:dw|

There are other ways to write it. What are the choices?

74/15 , 7-5sqrt 74/5, 7-sqrt74/15 or 74/21

Then, the ratios you gave for tan and csc must be wrong. Where did you get those from?

|dw:1326988372290:dw|

I first had to find the missing side then use the ratios

What is A and B and C?

Well, before I say that I found C by using the pythagorean therom and got sqrt 74?

Ok wait... let me post the letters

|dw:1326988584560:dw|

Sorry for the messiness lol

Now subtract and you will get the right answer.

|dw:1326988606286:dw|

That is equal to 3x. Now, x will be equal to 1/3 of that value.

|dw:1326988707325:dw|

So you multiplied both sides by 5?

WOOHOOO!! Thank you so much I got a 100!

Thanks everyone

Great. Hope you also now can solve such problems with ease!

I do to lol!
