Atree with a height of 12 yards casts a shadow that is 33 yards long at a certain time of day. at the same time, another tree nearby casts a shadow that is 20 yards long. how tall is the second tree? a. 8.0 yards b. 7.7 yards c. 7.3 yards d. 6.3 yards e. 6.1 yards

7.3 yards

Step-by-step explanation:

Given :A tree with a height of 12 yards casts a shadow that is 33 yards long at a certain time of day.

At the same time, another tree nearby casts a shadow that is 20 yards long.

To Find:  How tall is the second tree?

Solution:

Let the length of another tree be x

Length of first tree = 12 yards

Length of shadow of first tree = 33 yards

Length of shadow of second tree = 20 yards

There is a direct variation between length of tree and length of Shadow .

A.T.Q

So, the height of the seconds tree is 7.27 ≈ 7.3 yards

Hence the height of the second tree is 7.3 yards

So, Option C is correct.
