Question

Been stuck on this question for a while now...

Answer 1

i can see why

Answer 2

Grace is standing 14 feet from a lighthouse and Kelly is standing 12 feet from Grace. The angle that Grace looks up to see the top of the lighthouse is 45°. The angle that Kelly looks up to see the top of the lighthouse is y°.

Answer 3

I need to find the height, and the angle in which Kelly is looking at the lighthouse.

Answer 4

first solve for height.

Answer 5

tan(45)=height/14

14tan(45)=height

Answer 6

then you have 14+12=26

tan(theta)=height/26

or tan(theta)=14tan(45)/26

Answer 7

arctan(14tan(45)/26)= angle of y

Answer 8

that is assuming kelly is standing 12ft from gracy, rather then 12ft infront of gracy.

Answer 9

Okay, so the height would be 45 since the tan of 45 is 1? Or would it be 14, reading it as 14 x the tan of 45?

Answer 10

it would be 14

Answer 11

so you can subsitute 14 for 14tan(45) in the other parts

Answer 12

to make it simpler

Answer 13

Alright, thanks so much man :) I'll give you your medal here in a second.
