Question

a contractor wants to set up a slide children to play in the park.He wants to set it up at height of 2m and by making an angle 30 with ground.what should be length of the slide
​

Answer 1

Answer:

Step-by-step explanation:

Hi there,

Consider question as a right

angled triangle.

Height of slide = 2m (Opposite side)

Length of slide (Hypotenuse)

 

Using the angle of 30 degrees we have:

Sin = Opposite/Hypotenuse

Sin 30 = 2/Hypotenuse

Hypotenuse = 2/sin 30

Hypotenuse = 4

So, slide should be 4m long.

Hope this helps:-)

Answer 2

Answer:

Step--step explanation:

Let length of slide be x

Considering sin 30

Sin30=2/x

We know that sin 30 is1/2

By putting value of sin 30

We will get

1/2=2/x

By cross multiplication

X = 4
