Answer:

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

Step-by-step explanation:

The image attached shows a representation of this problem.

First, we use the sine trigonometric reason to find [tex]y[/tex]

[tex]sin30\°=\frac{y}{3.5}\\\frac{1}{2}=\frac{y}{3.5}\\ y=\frac{3.5}{2}=1.75 m[/tex]

Now, the height of the kite is

[tex]h=1.75m+80cm[/tex]

But, first we need to transform from meters to centimeters

We know that 1 meter equals 100 cm, so

[tex]1.75m\frac{100cm}{1m} =175cm[/tex]

Then,

[tex]h=175cm+80cm=255cm[/tex]

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