As the question is stated, Tom is standing IN THE TOWER'S SHADOW. If so, then Tom can't cast a shadow of his own, because he is not illuminated. Let's assume the question means to imply that Tom's shadow is measured AT THE SAME TIME that the shadow of the tower is measured, and kind of NEAR the tower, so that the sun casts both shadows from the same place in the sky. If this is a valid assumption, then the tower is 12 meters tall.
10.08 feet approx.
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).
25 meters because 25/20 = 15/12 which is the tangent ratio.
The ratios are in the same proportion, so all you need to really figure out is what is in the same ratio to 20 as 6 is to 4.

Not enough information has been given to solve this problem such as: What is the angle of elevation?
It works out as 15 feet
40 meters
inverse of tan(h/6). where h=height of street post in meters.
10.08 feet approx.
If the building casts a shadow, then the sun is out, and any man who is not standing in theshadow of the building will cast a shadow of his own, no matter how short or tall he may be.(If you had told us the length of the man's shadow, it would have been a completely differentquestion, and we could have had a completely different answer to offer in response.)
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).
The tree is 34.5 feet tall because tangent ratio of 34.5/24 = 5.75/4
It is: 27.35 degrees rounded to two decimal places
25 meters because 25/20 = 15/12 which is the tangent ratio.
Earth casts the shadow.
