It looks equivalent.
Do the Pythagorean theorem on the triangle shown.
2.1^2-1.4^2
4.2-1.96=2.24
Sqrt of 2.24 is 1.496 or 1.5
Now multiply this by 2 to get the length of x
HOPE THIS HELPS
40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
