One afternoon, the shadow of a flagpole is 21 feet long. At the same time, the shadow of a 109-foot-high building is 54 feet long. What is the approximate height of the flagpole?

10 ft

42 ft

72 ft

76 ft

sorry, can't i suggest going to algebra.com

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
