Please indicate subject, not grade level. That will help increase the chances that the appropriate teacher reads your question.
Because of similar-triangle geometry rules, the ratio of shadow length to the height of the object casting the shadow is a constant. If the tree height is x,
25/x = 9/6
Solve for x.

25/x = 9/6 (where 25 is the tree's shadow, x is the unknown height of the tree, 9 is the man's shadow and 6 is the man's height)
solve for x
cross multiply 25(6) = (9)x
150 = 9x
x = 150/9
do the division
x = 16.6
the tree is 16.6 feet or about 17 feet tall
25/x = 9/6 (where 25 is the tree's shadow, x is the unknown height of the tree, 9 is the man's shadow and 6 is the man's height)

cross multiply 25(6) = (9)x
150 = 9x
x = 150/9
do the division
x = 16.6

A tree that is 100 feet tall casts a shadow that is 150 feet long. Determine the angle at which the rays of the sun hit the ground, to the nearest degree.

6/x = 9/25
9x = 150
x = 150/9
x = 16.666.../16.7/17 feet
9x = 150
x = 150/9
x = 16.666.../16.7/17 feet
