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.

x=half

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
