Mrs. Canter's math class went outside and plucked blades of grass and then measured them. The line plot shows what fraction of a
n inch 12 of the blades of grass were. What is the difference of the length of the shortest blade of grass and the length of the longest blade of grass? Write your answer as a mixed number in simplest form.

Because x is not defined, it is assumed to be the height of the balloon.
Note that
75° 20' = 75.333°
49° 30' = 49.5°
From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x
Because a + b = 400 ft, therefore
0.8541x + 0.2617x = 400
1.1158x = 400
x = 358.49 ft
Answer: 358 ft (nearest whole number)
