Answer:
H=22.5ft
Step-by-step explanation:
According to the graph, we must find y to determine the height at which the rope must be placed so that the lowest point of the rope is 17 ft high
.
applying the pythagorean theorem
[tex]h^{2}=x^{2} +y^{2}\\y^{2}=h^{2} -x^{2}\\y^{2}=30.5^{2} -30^{2}\\ y^{2}=930.25-900\\y=\sqrt{30.25}=5.5ft[/tex]
then H=17ft+5.5ft=22.5ft
