GRAFICO Y RESOLUCIÓN PASO A PASO

Answer 1

The kite is 255 centimeters from the ground level, which is equivalent to 2.55 meters.

Explanation:

The image attached shows a representation of this problem.

First, we use the sine trigonometric reason to find
`y`

`sin30\°=(y)/(3.5)\\(1)/(2)=(y)/(3.5)\\ y=(3.5)/(2)=1.75 m`

Now, the height of the kite is

`h=1.75m+80cm`

But, first we need to transform from meters to centimeters

We know that 1 meter equals 100 cm, so

`1.75m(100cm)/(1m) =175cm`

Then,

`h=175cm+80cm=255cm`

Therefore, the kite is 255 centimeters from the ground level, which is equivalent to 2.55 meters.
