The shadow:object ratio is 1:1 so the tree is 63 feet high.

It is approx 36.6 ft.

1.8 meters. The ratio of object to shadow is 10:6. Therefore if the object is 3, the shadow is 1.8 ( 6/10x3).
If the tree is T ft high, then T/21 = 8/3 so that T = 21*8/3 = 56 feet.

To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.

Not enough information has been given to solve this problem such as: What is the angle of elevation?
If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.
5.5/8 = x/20 x=5.5*20/8 = 13.75 feet
17.45 feet.
It is approx 36.6 ft.
(12 / 5) × 33 = 79.2 feet high Divide the pole shadow by the pole height: (12 / 5) = 2.4 feet Times the 2.4 by the tree shadow of 33 feet: 2.4 x 33 = 79.2
