-- On the width:
3 yards = 9 feet
12 inches = another 1 foot
Total width = 10 feet
-- On the length:
8 yards = 24 feet
Ratio of width to length = (10 feet) / (24 feet)
= 5 / 12 .
I'll do the first problem to get you started.
Triangle SRT is a right triangle with the 90 degree angle located at angle RST. This is because segment SR is an altitude of the triangle. Altitudes of a triangle go from a vertex to the opposite side, and they are perpendicular to the opposite side.
The acute angles of right triangle SRT add up to 90 degrees. They are complementary angles.
(angle SRT) + (angle STR) = 90
(4x-8) + (6x+13) = 90 .... substitution
10x + 5 = 90
10x + 5 - 5 = 90 - 5 .... subtract 5 from both sides
10x = 85
10x/10 = 85/10 .... divide both sides by 10
x = 8.5
Therefore the answer is choice A) x = 8.5

The standard deviation of the set is 5.2
To find standard deviation, we take the square root of the variance.
