Q:

Coach henry tied a rope to the top of a 6 ft pole andsecured the rope to the ground 6 ft from the base ofthe pole. How long is the rope?​

Accepted Solution

A:
Answer:8.49 feetStep-by-step explanation:From this scenario, a right triangle is created, where,Pole (6ft) is left side of triangle,Ground Distance (6ft) from pole to where rope is secured is the base of the triangleHence, the rope itself is the HYPOTENUSE of the triangle (hypotenuse is the side oppose of 90 degree angle -- this angle is created with ground and pole)Now that we know both legs of the triangle are 6 each and we need to find hypotenuse, we use the Pythagorean Theorem to solve this:Pythagorean Theorem is Hypotenuse ^2 = Leg^2 + AnotherLeg^2Here,Leg = 6AnotherLeg = 6So we write and equation and solve for Hypotenuse (h):[tex]h^2=6^2 + 6^2\\h^2 = 36 + 36\\h^2 = 72\\h=\sqrt{72} \\h=8.49[/tex]The rope's length is 8.49 feet (rounded to 2 decimal places)
