Question

Find the height of the basketball hoop

Answer 1

Answer: 13.51 (not in inches format)

Explanation:

tan(x) = 4.384/12

x = tan^-1 (4.384/12)

x = 20.068°

tan(20.068) = y/(12+25)

tan(20.068) = y/37

20.068 = tan^-1 (y/37)

y = 13.51

Answer 2

Explanation:

To solve this with similar triangles - you need to set up a proportion.

I changed it all to inches.

12 ft = 144 in

4.384 ft = 51. 84 inches

12 + 25 (you need to add the base of the triangle) = 37 ft = 444 inches

set up smaller triangle in proportion to bigger triangle

51.84"/144" = x/444

cross mulitply then divide

51.84 times 444 = 23016.96

23016.96 ÷ 144 = 159.84 inches

Change back to feet by dividing by 12

159.84 ÷ 12 = 13.32 ft
