No I really don't know how to do it

Answer 11

ok i got u

Answer 12

first draw triangle between tha boat, tha top of tha cliff, and tha bottom of tha cliff

Answer 13

the horizontal distance from tha boat to tha base of tha cliff is 967ft

Answer 14

Okay, I've got everything drawn out but I don't know how to solve it

Answer 15

yea thass tha problem im having

Answer 16

u got it??

Answer 21

I honestly have no idea..I think it's right.. did you figure it out?

Answer 22

not yet..i cant do this in my head let me get my calculator

Answer 23

arctan (sin (pi/2))
sin (pi/2) = 1
arctan 1 = pi/4

cliff's height H is the side of a right triangle having
opposite angle 15°54' and the other side 967ft

H = 967 tan(15°54') = 275ft

Is this correct?

Answer 24

i really dont think my answer is right....275.46 and hope its right

Answer 25

hahaha thanks

Answer 26

ur welcome...sorry i couldnt hlp more but im not really familiar with pre-cal

Answer 27

It's all good at least you tried! Have a good one! (:

Answer 28

u too and if u need hlp with anything else jus let me kno:)
