Answer:
h = 14.49 feet.
Step-by-step explanation:
From the attached figure,
Base = 14 ft
Height = h
Angle = 46°
We need to find the height of the main sail. To find it we can use trigonometry.
The relation between height, base and angle is given by :
So, the height of the main sail is 14.49 feet.
4 and 3/4
the number line goes like this: 4, 4 and one fourth, 4 and a half, 4 and three fourths, then 5.
Surface area = 12*9 + 2*12*10 + 2*9*10 = 528 in^2 Answer
(its only one 12*9 because it is open at the top)
