Question

A baseball diamond is actually in the shape of a square 90ft. on one side. Suppose that a third baseman fields a ball while standing on the third base line 8 ft. from third base. how far is the third baseman's throw to first base?

Answer 1

It is right triangle with legs 82 and 90. They hypotenuse is the path of the thrown ball.

pythagorean says: sqrt( 82^2 + 90^2) = 121.75+

just over 121 feet 9 inches
