help !?!? Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)

Well what trig function would we use here knowing that we have the adjacent side and the hypotenuse

OpenStudy (anonymous):

cos

OpenStudy (johnweldon1993):

Right...so it would be set up like \[\large cosy = \frac{8}{13}\] And since we want to solve for the angle...we would do the inverse... \[\large y = \cos^{-1} \frac{8}{13}\] what do you get when you do that?

52.02012756

OpenStudy (johnweldon1993):

And that is your 'y'!

OpenStudy (johnweldon1993):

Just remember to round to the nearest hundreth

OpenStudy (anonymous):

how??

OpenStudy (johnweldon1993):

So we have 52.02012756 |dw:1387680337058:dw| so this rounds just to 52.02 since the number after the 2 is < 5
