Mike has 10 and a half cookies (10.5). Mike wants to share these cookies with 5 friends. How many cookies does each friend get. The answer is 2.1 one (Or 2 and 1 crumb I guess lol). You place the decimal point where ever it was originally so you would place it after the 2 and before the one. It's been a while since I've done one of these problems so sorry if I'm a little rusty.
Im pretty sure the answer is a
Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
I believe the answer would be -2 and -11 hope this helped!
