BLEEEEEEEEH

anonymous · Answer

not helping?

experimentx · Answer

$$ \sin 50 = 100/x$$
find x using calculator

kymber · Answer

Can you explain, though!!?

experimentx · Answer

$$ \sin \theta = p/h$$
the question is asking you to find h ... and also note this is a right angled triangle

anonymous · Answer

trig ratios is what you need to know for these

anonymous · Answer

btw it is not sine in this case but tangent i think

kymber · Answer

I know the trig ratios, SOH CAH TOA

anonymous · Answer

oh no, it is sine my fault!!

anonymous · Answer

should have known better.
do you know the trig ratios for a triangle?

kymber · Answer

Is it not SOH CAH TOA?!?!!?!

anonymous · Answer

so for the angle given , lets call it $x$ in terms of $a, b, c$ can you say what 
$$\sin(x)$$ is?  
you are right, you can use soh cah toa if you know what they mean

anonymous · Answer

so in your picture, you are trying to find the hypotenuse $h$ so you know from "SOH" that the sine of 50 is the opposite over the hypotenuse, or 
$$\sin(50)=\frac{100}{h}$$ and then you solve for $h$ via 
$$h=\frac{100}{\sin(50)}$$

anonymous · Answer

got that or still confusing?

kymber · Answer

Uuh, I think I got itt, thanks a bunch for helping meee! :D
