For Erin, the graph shows 10 pounds of sugar are used for every 30 cups of tea.

For Lucia, we can let x=3 and we find 3 pounds of sugar are used for 10·3 = 30 cups of tea.

For the same number of cups of tea (30), Erin uses 10 pounds of sugar and Lucia uses 3 pounds of sugar.

Erin uses sugar at a higher rate.

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
