Question

Please Help with 35. I’m confused.

Answer 1

Answer: A

Explanation:

First, you need to find the length of diagonal of the bottom base

length of bottom diagonal

use Pythagorean theorem

`a^(2) +b^(2) =c^(2)`

a = 4

b = 2

`4^(2) +2^(2) =c^(2)`

`20 =c^(2)`

we will leave
`c^(2)` like this for the next part

length of LM

use the Pythagorean theorem again

this time,
`c^(2)` is one of the legs

`c^(2) +d^(2) =LM^(2)`

`c^(2) = 20`

`d^(2) = 2^(2) = 4`

`LM^(2) = 20 + 4 = 24`

`LM = √(24)`

answer choice A
