Ineed with this geometry question asap !

You must apply this:
SOH CAH TOA

S means sine. O means opposite. H means hypotenuse. C means cos. And T means tan.

Applying this now you would write: cos 55°=80
—-
x

Now solve for x:

cos 55°(x)= 80
————— ——-
cos 55° cos 55°

Now type 80/cos 55° in your calculator and you should get 139.4757 which would round to 139.5

Cos55 = 80 / x. Use your calculator to get x = 139.48

The answer would be 13.5 minutes.
