When flying a kite, Peter lets out 45 ft of string and anchors it to the ground. He determines the angle of elevation of the kite is 63°. What is the height of the kite from the ground? Round to the nearest tenth.
since you have a triangle- formed by the ground and the height and the string, you can use trig.
in trig the Sin = opposite over hypotenuse since your angel is 58, and it is the angle of the string off the ground, then sin58=opp/hypotenuse sin58=x/45 ^^^ here, x is the height (what youre looking for), and 45 is the string lenght multiple the whole thing by 45 to get 45sin58=x then on your calculator do sin(58) then take that answer and multiply by 45 this answer is the height of the kite in yards!
