techincally we can't solve because his hands are below his head so we can't find the right answer
whatever
use pythagorean theorem
for a right triangle
if the legs are length a and b and the hytponuse is c then
a²+b²=c²
the hyptonuse is the longest side
so
the legs are 200ft and x and the hyponuse is 220ft
200²+x²=220²
40000+x²=48400
x²=8400
sqrt both sides
x=√8400
x=20√21
x≈91.6515
round
x=91.7ft
