I would use the Law of Sines to solve this problem.
The angle next to the 58 degree angle is 122 degrees. The side opposite this angle is 3.72 km.
The angle we need to find is at the cave. The side opposite this angle is 2.60 km.
(Sin 122/3.72) = (Sin x/2.60)
Cross multiply to solve.
3.72 Sin x = 2.60 Sin 122
Divide both sides by 3.72
Sin x = (2.60 Sin 122)/3.72
Sin^-1 x = (2.60Sin122)/3.72
x = 36 degrees

A landscaping company placed three orders with a nursery. The first order was for bushes, trees, and bundles of flowers, and tot
notsponge [240]

To add the bushes and trees, to get 19 bushes and 6 trees, but this wouldn't get me anywhere, because I don't have subtotals for the bushes and trees.

So I'll pick variables (b for the number of bushes and t for the number of trees) and set up a system of equations:

first order: 13b + 4t = 487

second order: 6b + 2t = 232

Multiplying the second row by –2, I get:

13b + 4t = 487

–12b – 4t = –464

This says that b = 23.

Back-solving, I get that t = 47.

Of course, the exercise didn't ask for the values of the two variables. Translating back into English, the solution is,

each bush is $23 and each tree is $47.
