Solve the problem.
-Your math class is going to test new digital clinometers by measuring the angle of elevation of a kite you will fly. The kite flies to an angle of 68.9° on 360 feet of string. Assuming that the string is taut, how high is the kite
To the nearest foot?
A) 130 ft
B) 933 ft
C) 336 ft
D) 386 ft

Quizplus · Accepted Answer

The height of the kite can be found using trigonometry, specifically the sine function, since we have the angle of elevation and the length of the string. The sine of an angle in a right triangle is equal to the opposite side (height of the kite) divided by the hypotenuse (length of the string). So, sin(68.9°) = height / 360. Solving for height gives height = 360 * sin(68.9°). Using a calculator, this gives a height of approximately 336 feet.
