4 6 points A 150foottall building casts a shadow of 30 ft at

4) (6 points) A 150-foot-tall building casts a shadow of 30 ft at the same time that a flag pole casts a shadow of 4.5 ft. How tall is the flag pole?

Solution

We have to use the property of similar triangles

Height of building /height of shadow = height of flagpole/height of flagpole\'s shadow

150/30=h/4.5

h=22.5 foot

Height of flagpole = 22.5foot
