Question

A ladder 15 feet long leans against a wall and forms an angle of 45º with the ground. How far from the wall is the ladder?

Answer 1

Think of your trigonometry functions. Which would work here?

Answer 2

Am i correct i tried solving it. 7.5 ft?

Answer 3

I'm really bad at math.

Answer 4

no i got 15.6...

Do you know SOH CAH TOA?

Answer 5

no

Answer 6

sorry 10.6 lol i typed that wrong...

SOH(sin) = opposite/hypotenuse
CAH(cos) = adjacent/hypotenuse
TOA(tan) = opposite/adjacent

Answer 7

in this case we need adjacent and hypotenuse so use CAH

cos(45) = x/15

x = 15cos(45) = 10.6
