A builder makes drainpipes that drop 1 cm over a horizontal distance of 30cm to prevent clogs a certain drainpipe needs to cover a horizontal distance of 700cm whats is the length of the drainpipe? round your answer to the nearest tenth of a centimeter

Step-by-step explanation:

Given a builder makes drainpipes that drop 1 cm over a horizontal distance of 30cm to prevent clogs. The ratio of the vertical drop to the horizontal distance covered is cm.

The angle of inclination,

tan(θ) =

θ = 1.9º

By trignometric ratio,

cos(θ) =

length of the drainpipe = =

length of the drainpipe = 700.7 cm

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

54/3 is 18 so 18 is your answer
