Question

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

Answer 1

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

Answer 2

cos

Answer 3

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?

Answer 4

52.02012756

Answer 5

And that is your 'y'!

Answer 6

Just remember to round to the nearest hundreth

Answer 7

how??

Answer 8

So we have 52.02012756




so this rounds just to 52.02 since the number after the 2 is < 5

Answer 9

thx

Answer 10
