#### Answer

127.3 ft

#### Work Step by Step

Use the Pythagorean Theorem. Let d be the distance from home plate to 2nd base. The distance between each base is 90 ft.
$d^2=90^2+90^2$
Simplify.
$d^2=8100+8100$
$d^2=16200$
Take the square root of each side.
$\sqrt{d^2}=\sqrt{16200}$
Simplify and round.
$d\approx127.3$
