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

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

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

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
\[h=\frac{100}{\sin(50)}\]
