Miniature Golf Paint that Pole!
9
Sherwin Williams Paint Company has called upon the group Sherman Millions for help in renovating the SHS football stadium by painting its light poles. The dilemma is, they have no clue how much paint is needed to do so. Therefore, they recruited our aid to solve another unascertained surface area measurement.

Solution to Trigonometric Solution to Trigonometric ProblemProblem
Height of home side pole:
1. tan 28= x/y tan 28y=x 2. tan 25= x/y+10 tan25y+tan 25 (10)=x tan 25y+tan 25 (10)=tan 28y tan 25 (10)=.06540y 4.66308 = .06540y .06540 .06540 y = 71.30092
tan 28 (71.30092)=x ~ x = 37.91137 m + 1.53 m — height of person
39.44137 m - .42 m — base 39.02137 m HEIGHT OF HOME POLE = 39 m
Height of away side pole:
1. tan 27 = x/y tan 27y = x 2. tan 22= x/y+10 tan 22y + tan 22 (10) = x tan 22y + tan 22 (10) = tan 27y tan 22 (10)= .10550y 4.04026 = .10550y .10550 .10550 y = 38.29630
tan 27 (38.29630) = x ~ x = 19.51294 m + 1.53 m — height of person 21.04294 m HEIGHT OF AWAY POLE = 21 m
