. Using the Distributive Property and Addition Propert of Equality, we can simplify this equation into 
by factoring -5/4 into (x-4) and subtracting 9 from both sides.
Answer: 63.39 ft
Step-by-step explanation:
A. 20
Sims angles C and B are each 80 degrees, angle A must be 20 degrees
At a certain time of day, a 5.5 foot tall man has a 6 foot shadow. if a tree is 19.25 feet tall, what is the length of the shadow of the tree(x=shadow of the tree)
the equation for the problem is...
5.5/6=19.25/x
you then multiply the denominators on both sides...
5.5x=19.25*6
you then solve on one side...
5.5x=115.5
and then divide 5.5 on both sides to leave x alone...
x=21
the shadow of the tree is 21
