21 feet

Step-by-step explanation:

The dimensions of the 'triangle' between the tops of the 2 poles measures 6 ft x 18 feet. That means the length of a completely tight string of lights is:

Because you are adding 2 feet of slack, you will need 18.973665961 ft + 2 ft, which is 20.973665961 , which rounds to 21 feet

C. 21 ft

Step-by-step explanation:

See the attachment.

According to the picture, we see that the string of lights is actually the hypotenuse of a right triangle. One leg of this triangle is the same distance as the street between the two buildings, so it's 18 ft. The other leg is simply the difference in heights of the two buildings: 26 - 20 = 6 ft.

Finally, the hypotenuse can be found by using the Pythagorean Theorem:

x = √(6² + 18²) ≈ 18.97 ft

However, Evan wants 2 ft of slack, so add 2 to 18.97: 2 + 18.97 = 20.97 ≈ 21 ft

The answer is C.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
