An electrical tower casts a 120-foot shadow. at the same time, a 10-foot
street sign casts a shadow of 8 feet. what is the height of the tower?

o a. 270 ft
o b. 150 ft
o c. 120 ft
o d. 180 ft

Set up a ratio with the height over the shadow.

Let the height of the tower be X

The ratio of the tower is x/120

The ratio if the sign is 10/8

Set them to equal and solve for x:

x/120 = 10/8

Cross multiply:

8x = 1200

Divide both sides by 8:

x = 1200/8

x =150

The answer is B. 150 ft.
