in this case, the length of the kite string is the hypotenuse of a triangle, we will label ABC
we know that side length a is 19m, and the angle A is 33°. (remember side a and angle A are always opposite each other, same as side b and angle B etc.) From this information we can use SinФ = Opposite/Hypotenuse
1. fill in the information you know
Sin33°=19m/x
2. solve for sin33°
0.55=19m/x
3. Isolate x
x = 19/0.55
4. Solve
x = 34.5m
∴the length of the kite string is 34.5 m
