Question

A kite is attached to a string. Find the length of the string,when the height of the kite is 60m and the string makes an angle 30° with the ground.

Answer 1

Answer:

120

Step-by-step explanation:

height of kite h = 60m

let length of string be x(hypotenuse)

sin 30° = h/x = 60/x

1/2 = 60/x => x = 120 m

Answer 2

$\huge\star{\green{\underline{\mathfrak{Answer :-}}}}$

Figure attached.

GIVEN :-

• AC = 60 m
• Angle ABC = 30 deg

TO FIND :-

• AB

SOLUTION :-

We know,

$\sin 30°= \dfrac {Perpendicular}{Hypotenuse}$

$\dfrac {1}{2}= \dfrac {60}{Hypotenuse}$

So, Hypotenuse = 120 m.

Other formulas :-

• sin theta = Perpendicular/Hypotenuse
• cos theta = Base/Hypotenuse
• tan theta = Perpendicular/Base
• cosec theta = Hypotenuse/Perpendicular
• sec theta = Hypotenuse/Base
• cot theta = Base/Perpendicular
