Question 1209516
<font color=black size=3>
I'll assume the two friends start at the same location.
{{{
drawing(400,400,-3,3,-4,3,
line(-2,-3,2,-3),line(2,2,2,-3),line(2,2,-2,-3),
line(2,-3+0.32,2-0.32,-3+0.32),line(2-0.32,-3+0.32,2-0.32,-3),
locate(0,-3.3,5),locate(2.4,-0.34,4),locate(-0.3,0,"x"),
locate(-3,2,matrix(1,4,"Diagram","not","to","scale"))
)
}}}
{{{a^2+b^2 = c^2}}} Pythagorean Theorem
{{{4^2+5^2 = x^2}}}
I'll let the student finish up.
