Question

Somebody help please

Answer 1

`√(2000)\phantom{a}yards`

Explanation:

For a right triangle,
`a^(2) =b^(2) +c^(2)`, if a is the hypotenuse. So,
`60^(2) =40^(2) +c^(2)`, and c is the the distance we are trying to find:

`60^(2) =40^(2) +c^(2)`

`3600=1600+c^(2)`

`c^(2) =2000`

`c=√(2000)\phantom{a} yards`
