Sum of w & 3.4 (3.4+w) is greater than or equal to (<span>≥) 10.5
</span>
Answer is: 3.4+w <span>≥ 10.5</span>
The answer is B. Take the same point on each of the figures and count how far they are away horizontally and vertically.
Calculate the length of each path using the law of cosines:
AB = √(8^2 + 8^2 - 2*8*8*cos(36)
AB = 4.94 ft.
XY = √(8^2 + 8^2 - 2*8*8*cos(79)
XY = 10.18 ft.
ZY = √(8^2 + 8^2 - 2*8*8*cos(65)
ZY = 8.60 ft.
XY is longer than ZY and ZY is longer than AB
The first choice is correct.
Answer: a:b:c:d = 16:24:30:40
You can also divide the ratio by 2 because all terms have 2 in common. Which would be a:b:c:d = 8:12:15:20
