The ratio of building heights will be the same as the ratio of shadow lengths. (taller building)/(shorter building) = (longer shadow)/(shorter shadow) (taller building)/(84 ft) = (110 ft)/(46 ft) . . . . . . fill in the given numbers (taller building) = (84 ft)*(110/46) ≈ 200.9 ft . . multiply by 84 ft, evaluate
There is a difference of 14 units between -2 and 12. To find the coordinate in the middle, just add 7, half the distance between -2 and 12, to -2 and subtract 7 from 12. That gives you the coordinate 5.
