Question

Which equation would you use to find the distance to the iceberg?





cos80 = 30/d

tan80 = 30/d

tan80 = d/30

Answer 1

HI!!

Answer 2

Help please

Answer 3

you got \(30\) and \(D\) and \(80^\circ\) you need an expression that combines them
you do not need the hypotenuse of that right triangle, just the two legs

Answer 4

use "tangent is opposite over adjacent"
the side opposite the \(80^\circ\) angle is \(D\) and the adjacent sides is \(30\)

Answer 5

that makes
\[\tan(80^\circ)=\frac{D}{30}\]

Answer 6

Thanks so Much :)
