How tall is a tree which cast a 20 meter shadow when a 3 meter post cast a 5 meter shadow?

They both have the same tangent ratios so let the height of the tree be x:-
x/20 = 3/5
Multiply both sides by 20
x = 60/5
The tree is 12 meters tall

Thomas happened to notice that like at 4 oclock pm on his unlces farm a fence post that was 5 ft tall cast a 2 foot shadow he also noticed that a nearby tree cast a 10 foot shadow how tall is the tree?
The ratio of the shadow cast to the height of an object will be the same at the same time of day. For the fence post, the height of the post is 2.5 times the length of the shadow ( 5 ft / 2 ft = 2.5 ) The tree has a 10 foot shadow, so using the same ratio for the fence post: 10 ft * 2.5 = 25 feet. The tree is 25 feet tall

A 40ft tall mounument casts a shadow that just reaches the base of a 4ft tall parking meter if the parking meter's shadow is 6.5 ft long how far apart are the monument and the meter?
The shadow of the 4 foot parking meter's shadow is 6.5. The shadow of the 40 foot tall monument has to be 65 (4/6.5 = 40/x so x is 65) a2+b2=c2 402+b2=652 1600 + b2 = 4225 b2 = 2625 b = about 51.2347 feet apart
