The class 4S because you divide each number by its mean mark and standard division and 4S is the highest.
Answer:
26 feet
Step-by-step explanation:
w: width
w+4 : length
w(w+4) = 572
w² + 4w - 572 = 0
w² + 26w - 22w - 572 = 0
w(w+26) - 22(w+26) = 0
(w-22)(w+26) = 0
w = 22, -26
width = 22 feet
length = w+4 = 22+4 = 26 feet
125/1000 because half of 0.5 is 0.25 and half of 0.25 is 0.125 and 0.125 is 125/1000
20 degrees
vertical angles are equal, so 5x-80=x
solve for x and you get 20
