Question

A ladder 35 feet in length rests against a vertical wall. The foot of the ladder is 10 feet from the wall. What angle, θ, does the ladder make with the ground?

Which of the following equations can be used to solve the problem?

cosθ = 10/35
sinθ = 10/35
tanθ = 10/35

Answer 1

remember these rules
cos is adjacent/hypotenuse
sin is opposite/hypotanues
tan is opposite/adjacent

so the number 35 and 10 represent what? adjacent, hypotenuse, or opposite?

Answer 2

Hypotenuse and adjacent?

Answer 3

yep ^_^
