Question

Solution

Finding the length of the string:

Step 1: Draw the figure from the given data.

From the given data, the figure is

Here,BC=Height of the kite from the ground, BC=60m

AC=Inclined length of the string from the ground and A is the point where string of the kite is tied.

Step 2: Find the length of the string from the ground i.e. the value of AC

sin60°=BCAC32=60ACAC=403m

Thus, the length of the string from the ground is 403m.
