That upside down u looking thing is the " intersection " of sets a and b. That means only the numbers that are in both sets.

so leg A would be 60

leg B would be 85

using this we are able to determine the HYP to be 104.04

so sine = opp/HYP

leg A is the opp in this case

sin(theta) = 60/104.04

sin(theta) = 0.57670126874

when we round to the hundredths place we get 0.58
