Well the 2nd one in the first row on the first page is 4.33. What you do first is figure out what you’re given and what your looking for. So you’re given the length of the hypotenuse which is 5, the 60 degree angle, and your trying to find the opp. And your trying to find the sin bc the sin is opp/hyp. So set it up like sin60 = x/5 and then you solve by doing 5 • sin60 in your calculator. This is so hard to explain so I would recommend looking up a vid about it online
