Miguel is 5 feet 10 inches tall. On a sunny day he casts a shadow 4 feet 2 inches long. At the same time, a nearby electric tower casts a shadow 8 feet 9 inches long. How tall is the tower?

Respuesta :

what is the rest of the question is that it?
height of man /shadow of man = height of tower/shadow of tower. 

notice I set up "like things" in the same pattern 

(5 10/12) / (4 2/12) = height of tower/(8 9/12) 

(35/6) / (25/6) = tower/(35/4) 
tower = (35/4)(35/6) / (25/6) 
= 49/4 inches or 12 ft 3 inches
