Question

Joe strung a 12-yard rope from the bottom of one flagpole to the top of another. Hemeasured the angle of elevation of the rope as 38°. What is the distance between thetwo flagpoles in yards? Round to the nearest tenth.

Answer 1

the triangle

cos (38º) = adjacent side / hypotenuse

adjacent side = cos(38º) * hypotenuse

adjacent side = cos(38º) * 12- yard

adjacent side = 9.4561

Rounded to the nearest tenth

adjacent side = 9.5
