First, create an equation with the criteria given.
If we let x be your number,
(
is twice the product of 3 and x, and if it exceeds
by 10, then we add 10 to
to make the two sides of the equation equal.)
Now, solve for
.
Answer:
/\
Step-by-step explanation:
Set up ratios of height / shadow length:
8/6 = x/100
Cross multiply
6x = 800
Divide both sides by 6
X = 133.33 feet
The tower is 133.3 feet
The ratio can be determined as,
Thus, the requried ratio is 7:12.
