Question

Please help, taking exam and completely lost):
Look at the figure below:
if csc x=3/2, what is the value of y?
a)1/2
b)1/4
c)4/3
d)8/3

Answer 1

Do you mean you're taking the exam right now?

Answer 2

yeah and unfortunately this is my hardest subject /:

Answer 3

But we can't help you cheat in your exam, I think..

Answer 4

no you can't ,but an explanation doesn't hurt right ?

Answer 5

the only thing im aware of is that csc is a reciprocal of sine

Answer 6

cscx = 1/sinx
sinx = opposite side to the angle x / hypotenuse.
This might help you a bit, well, I can't tell you more than that, I think.

Answer 7

You can use computers at school?

Answer 8

well thank for the advice roly , and yes nicole but today is saturday, im using my home computer

Answer 9

oh
thanks

Answer 10

@RolyPoly im having problem understanding your equation, should i just plug in the numbers?

Answer 11

numbers and variable.

Answer 12

no i don't understand.. well ill seek help from another source, thanks.

Answer 13

csc x = 1/sin x = hypotenuse/opposite side

Answer 14

my problem is that i dont know how to solve it,im aware of the formula but no one is explaining the steps....

Answer 15

What is the opposite side in the figure?

Answer 16

@phi I think the 4 next to y is the coefficient of y.

Answer 17

opposite side is the y right?

Answer 18

Not really.

Answer 19

Almost correct.

Answer 20

well it cant be 3 because its the hypotenuse so idk

Answer 21

Yes, 3 is the hypotenuse. But as I said, the opposite side is NOT y alone. There is a number before it.

Answer 22

so 4y is the opposite?

Answer 23

That's what I think.

Answer 24

Now, you can express cscx in terms of y. Since you have the value for cscx, given in the question, you can equate them and solve for y.

Answer 25

so csc = 3/4y?

Answer 26

Yes, well, cscx.
