x =
<u><em>2nd photo:</em></u>
(a) GEH ~ FGH ~ FEG
<em>similar triangles, use similar corners in the right order</em>
(b)
AND 
<em>similar triangles, use similar sides in proportion</em>

<u><em>3rd photo:</em></u>
x = 4.5 or 4 1/2

<em>2x = 9</em>
<em>x = 4.5 or 4 1/2</em>

<u><em>4th photo:</em></u>
Length of string = 118.2 ft
<em>sin(40) = 76/x</em>
<em>x = 76/sin(40) = 118.2</em>
step 2 would be 10
step 4 would be 10x-x = 9x =7
x = 7/9
4 for part A
17 for part B
Answer:
I'm assuming you have 4 options, and if so, the answer is A.
Step-by-step explanation:
Rounding 36.6 off to 37 will make it easier to estimate the quotient when dividing by 5. For example, I can easily come up with a solution in my head when dividing 37 to 5 but it's harder for me to come up with a solution to 36.6.
Let x = red
Let 0.5x = green
Let (x) + (0.5x) = 1.5x = blue
Let 0.5(1.5x) = 0.75x = yellow
Let 0.75x + 4 = brown





Use this value to calculate the other required numbers.
red = 28
green = 0.5x = 0.5(28) = 14
blue = 1.5x = 1.5(28) = 42
yellow = 0.75x = 0.75(28) = 21
brown = 0.75x + 4 = 0.75(28) + 4 = 25
