Geometry Question Bank #3

[deem432]

I don't understand why the answer to this question is not 169 (sqrt3) / 4.

Will someone please explain this to me? I am confused.

hi,
per the forum rules, please post the entire question, including all answer choices.

also, please give some indication of your own approach (i.e., how'd you get that number?)

thanks.
