Ответ:
24 Feets
Step-by-step explanation:
Using the diagram of the sketch illustrated in the attachment :
θ = 30.26°
Height(h) of tree house = 14 feets
Distance of treehouse to swingset = d
Using Pythagoras rule :
Tanθ = opposite / Adjacent
Opposite = 14 feets
Adjacent = d
Tan30.26° = 14 / r
0.5834166 = 14 / r
0.5834166 * r = 14
r = 14 / 0.5834166
r = 23.996571 Feets
r = 24 Feets (nearest whole number )
