For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.

h/(580 ft) = (5.5 ft)/(3 ft)

h = (5.5 ft)(580/3) ≈ 1063 ft

The height of the monument is about 1063 feet.

The figures are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.

Answer: Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

$ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}$

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

$\frac{256}{49}=\frac{x}{771}$

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

$x=(771)(\frac{256}{49})\\\\x=4,028m^2$

7, you divide the 14 by 2 because the qr is two times the length of gh, therefore 7 is two times the length of fh
