A ladder leaning against a building makes an angle of 68° with the ground. The foot of the ladder is 5.5 feet from the building.

How long is the
ladder?

Round to the nearest foot.
The ladder is WHAT feet long?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

36
