What is the distance between the points 21 30 and 3 8?
d = Root of((y" - y')2 + (x" - x')2) d = Root of ((30-8)2 + (21-3)2) d = Root of (22x22 + 18x18) d = Root of (484 + 324) d = Root of 808 = 28.425
What is the diagonal measurement of a 22x22 square?
In a right triangle, a2 + b2 = c2. So, the hypoteneuse, c = (a2 + b2)½. c = (222 + 222)½ = 968½ = (112 x 23)½ = 11 x 2 x 2½ = 22 x 2½ = 22 x 1.4142135623730950488016887242097... = 31.112698372208091073637151932613...
