There are 60 feet between the bases on a softball diamond. How far does a catcher throw drone home plate to second base

mixas84 [53]

Answer: $12\sqrt{5}$

Required theorem:

Pythagorean theorem = $a^2 + b^2=c^2$

In other words, one side length squared + another side length squared = the middle lined squared.

Step-by-step explanation:

$60^2+60^2 = c^2\\\\360+360=c^2\\\\720=c^2\\\\\ \sqrt{c^2} =\sqrt{720}\\\\c=+/- 12\sqrt{5}$

We can only have a positive distance so your final answer is :

$12\sqrt{5}$
