white : milk : dark
w : m : d
The ratio of white to not white is 3:4
w : (m+d) = 3:4
The ratio of not dark to dark is 17:4.
(w+m) : d = 17:4
---------
We treat the colons as fraction bars and cross multiply.
4w = 3(m+d) = 3m + 3d
4w + 4m = 17 d
Subtracting,
4m = 17d - (3m+3d) = 14d - 3m
7m = 14 d
m/d = 14/7
m:d = 2:1
Since w:(m+d)=3:4 let's make m+d a multiple of 4.
m:d = 8:4
w : (m+d) = 3:4 = 9:12
w:m:d = 9:8:4
Answer: 9:8:4
Check:
white to non white 9 to 8+4=12 = 3:4, good
non dark to dark (9+8):4=17:4, good

Remember that perimeter is the sum of the lengths of the sides. The way to find the length of the sides is

where

is one endpoint of one line, while

is the other endpoint of the same line. Repeat this formula for each side and add them all together to get your perimeter
Answer: 
Step-by-step explanation:
Let 'x' be the height of tree.
The length of shadow of a tree = 14 m
The length of shadow of a person =4 m
The height of person = 1.8 m
<em>Since both man and tree are standing vertical to the ground.
</em>
<em>Assume the formation of shadow is happening at the same time then the angle that the sun hits the earth making shadows of both person and tree will be equal.</em>
By direct proportion , we have
