i would help you, but i can't give out the answer.

shamil98 · Answer

You have the angle opposite to angle A and the hypotenuse, so you would use the sine function:
$$\sin x = \frac{ 3 }{ 9 }$$
Solve for x.

x= 0.33333?

***[isuru]*** · Answer

no...
 sin x = 0.333

***[isuru]*** · Answer

to find the x u have to find the inverse value of  sin x

***[isuru]*** · Answer

if       
       $$\sin \ x = 0.33$$
then
            $$x = \ \sin^{-1} 0.33$$

u have to use a trigonometric ratio table or a calculator.. can u continue it from here :p ?

anonymous · Answer

uhm, 37 degrees.? I don't understand

***[isuru]*** · Answer

if  u r using a calculator ( scientific cal on the pc) type 0.33 on the screen and press the button "inv" then press the button "sin^-1" and the value u  gt is the answer...

in fact it is 19.26 degrees

anonymous · Answer

so from the answers it should be b or a?

***[isuru]*** · Answer

it's b for sure :P
