Question

How long should the ladder be if they want to use all the cable they have? Use the law of sines to find the length, L.

a) L = sin(A) / sin(B)
b) L = sin(B) / sin(C)
c) L = sin(C) / sin(A)
d) L = sin(A) / sin(C)

Answer 1

The length of the ladder can be found using the formula L = sin(C) / sin(A).

Step-by-step explanation:

The correct formula to find the length of the ladder using the law of sines is L = sin(C) / sin(A). In this formula, L represents the length of the ladder, A represents the angle opposite to one of the known sides, and C represents the angle opposite to the unknown side (the length of the ladder). To use this formula, you need to know the measure of angle A and the length of one of the known sides. Plug in the values and solve for L.
