Hey there! :D
For this, you will need to draw your own diagram, but I think you can do this if I explain it. It should look like a triangle. Where the string is a vertex, and the kite is an upper vertex. The bottom is the distance. Look at the example. You can label the distances on it if you want to.
c= length of the string (75m)
b= height of the kite (62m)
a will equal the distance between Janet and the spot on the ground beneath the kite.
Now, we plug it into the Pythagorean theorem.
a^2+b^2= c^2
a^2+ 62^2= 75^2
Square the numbers.
a^2+3844= 5625
Subtract 3844 on both sides.
a^2= 1781
Find the square root.
√1781= 42.2 or 42.
I hope this helps!
