Linda is flying a kite. She lets out 45 yards of string and anchors it to the ground.?

Question

She determies that the angle of elevation of the kite is fifty eight degrees. What is the height of the kite from the ground?

Answer 1

sin 58 = h/45
45 * sin 58 = h
38.162 yards

Answer 2

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!

Answer 3

Do out the sine/cosine of the angle- whichever works for the problem
I think it'd be like 45sin58 (that works out to be 38.2yards off the ground), but I just did that off the top of my head. But look at if it should be sin or cosine

Answer 4

draw a picture
use the SOHCAHTOA method
sin= opposite/hypotenuse
cos= adjacent/hypotenuse
tan= opposite/adjacent


since the meausre of the angle is 50, and you need to know the lenghth of the line OPPOSITE of teh angle, and you know the HYPOTENUSE, the you use sin. (opposite over hypotenuse)
sin(50)= x/45
.766= x/45

x= 34.472



*****
damnit, i used 50 instead of 58
well its the same method
just substitue 58 in for 50 and work it out
you need a scientific calculator

Answer 5

use sine function.

sine = opp/hyp = height /string

h = 45 x sin 58 = 38.16 yd

Answer 6

let x be the height
sin58=x/45
x=45sin58=38.2yards
