Mary's kite is flying ablve the beach at the end of a 75-meter string. if the angle of elevation to the kite measures 68° and mary is holding the kite 1.2 meters off the ground, then determine the height of mary's kite flight.

We found h

See figure. The sine trigonometric ratio of the angle 68° is:

sin(68°) = h / 75 multiplied by 75 we get

75xsin(68°) = (h / 75)x75

75xsin(68°) = h resolvemos

69.54 m = h

Then we add 1.2 m with 69.54 m to obtain the height H, i.e.

H= 1.2 +69.54  

H = 70.74 m is the answer.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
