after determing the length of the water hose; you would have to be familiar with properties of the 30-60-90 rt triangle

Find the length of the line B^D, which is sqrt(24^2+18^2) then, as this is the base to the triangle ABD, the length AB satisfies the following trig. equation: BD=ABcos(30) as 30 degrees is the angle between BD and AB. hence AB is given by AB=BD/(cos(30)

OpenStudy (amistre64):

\[\frac{\sqrt{3}}{wh}=\frac{ad}{1}\]

might have that a little off ...

Goodness me, I'm terrible, The length AD required is given by AD=BD/tan(60)

OpenStudy (amistre64):

wh is to sqrt(3) as ad is to 1 wh/sqrt(3) = ad

OpenStudy (amistre64):

yep :)
