How do I do b) in the attached file?

≈ 81.6 m

Step-by-step explanation:

The model of the situation is a right triangle

let h be the height of the cliff

Using the tangent ratio in the right triangle

tan58° = = ( multiply both sides by 50 )

50 × tan58° = h

We have to add on the height her eye was above ground , then

h = 50 × tan58° + 1.6 ≈ 81.6 m ( to 1 dec. place )

answer: b i think

step-by-step explanation:

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
