A baseball diamond is a square with 90 foot sides. How far must the third baseman throw the ball to make it to first base?
1 Answer
Explanation:
there are two adjacent sides between third base and first base.
since the shape in question is a square, the two points are opposite.
the line between two opposite sides of a square is the diagonal.
the third baseman must throw along the length of the diagonal to make it to first base.
the length of one side of the square (and therefore each side) can be used to find the length of a diagonal.
pythagoras' theorem:
the diagonal is the hypotenuse,
since all sides of a square are equal,
the two can therefore be put under one variable.
it is given that
the length of the diagonal is
the third baseman must throw
