Question

A kite flying at a height of 55m is attached to a string which makes an angle of 55 degrees with the horizontal. What is the length of the string
as always, draw a diagram and review your basic trig functions. You will see that

55/x = sin55°
sin55=55/x
xsin55=55
x=55/sin55
x=67.14
Always draw a diagram to see what is happening.
Using trigonometry: SOH is used
sin(55)=opposite/hypotenuse
=55m/hypotenuse
Hyp(sin55) =55m
Hyp= 55m/sin55
Hypotenuse= 67.14 metres (2 decimal places)
