PLEASSEEEE HELP W THIS QUESTION!!!!

The diagram shows 5 ft student standing near a tree. The shadow of the student and the shadow of the tree end at point A. What is the height of the tree? Show all your work, and make sure to include units in your final answer.

Answer 1

The tree is 15 feet.

For every foot, there is a 1.4 foot shadow.

5 • 1.4 = 7

28 - 7 = 21

21 ÷ 1.4 = 15

You can also:

5 ÷ 7 = 0.714285714285714

0.714285714285714 • 21 = 15

Answer 2

x/28 = 5/7
x = 28 * 5 / 7
x = 20

answer
x = 20 ft
