Question

A badminton net is tethered to the ground with a

Answer 1

Answer:

5.5cm

Step-by-step explanation:

In the diagram, the given side is adjacent to the given angle and we are required to find the Hypotenuse.

Using trigonometry,

$cos\alpha =\frac{adjacent}{hypotenuse}$

$\alpha =50^{0} ; adjacent=3.5cm and length of the rope, Hypotenuse =3.5cm$

$cos 50 =\frac{3.5}{x}$

Cross multiplying

x X cos 50 =3.5

$x=\frac{3.5}{cos 50} =5.45 cm\\Length of the rope =5.5cm (correct to i decimal place)$
