Answer:
The height of the tree is 30 feet
Step-by-step explanation:
Let
h ----> the height of the tree
we know that
The tree casts a shadow that is 27 feet long
Your friend is 5 feet tall and casts a shadow that is 4.5 feet long
so
using proportion
Find out the height of the tree
This is the number of combinations of 4 from 12
12C4 = 12!
----------
4! 8!
= 12*11*10*9 11*5*9 = 495
-------------- =
4*3*2*1
A = 5/6B
A = 150.60
150.60 = 5/6B
150.60 / (5/6) = B
150.60 * 6/5 = B
903.60/5 = B
180.72 = B
180.72 - 150.60 = 30.12....u save 30.12 when buying from store A
10x15= 150
150/2= 75
Diagonal = 75
