Question 842722
I find the question quite funny.
Of the three measurements (the height of the flag pole, the length of the wire and the distance from the pole), the easiest to measure by hand is the distance from the pole. Just pace the distance- you don't have to climb the pole nor the wire to measure the distance.
25^2=24^2+x^2
625-576=x^2
49=x^2
x=7
