Justin is 74 inches and casts a shawdow that is 102 inches long. At the same time , a tree casts a shadow that is 39 feet long.

sineoko [7]

Answer:

The tree is 28 feet in height.

Step-by-step explanation:

This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.

74 / x = 102/39 Cross Multiply

102x = 74*39 The inches as a unit cancel out.

102x = 2886 Divide by 102

x = 2886/102

x = 28.29 feet
