Explanation Given: The wire is tied 18 ft from the base of the pole and the pole is extended to 26 ft above the ground, but the wire is tied to the pole at 2 ft from the top. Thus, the wire is 24 feet above the base of the pole. Theorem used: “ Pythagorean theorem: The Pythagorean theorem states that the square of the hypotenuse of a right angled triangle is equal to the sum of the squares of the legs.” Calculation: From the given figure, the legs of the right triangle are observed to be 18 ft and 24 ft. the length of the hypotenuse is the length of the wire. Then by Pythagorean Theorem ( Hypotenuse ) 2 = ( leg ) 2 + ( other leg ) 2 . Obtain the length of the hypotenuse as follows. Substitute leg = 18 and other leg = 24 in ( Hypotenuse ) 2 = ( leg ) 2 + ( other leg ) 2
