Welp cramming for my precal final in 8 days. Kinda nervous but I'm so thankful you have an archive of videos explaining everything I need to know. I am going to become very familiar with Brian McLogan in the next week. 😂😅

The answer should be~ square root of 2 +square root of 3 over 2.

[@brianmclogan]

it is not an approximate, that is the exact answer

[@4snailssake]

@@brianmclogan hes saying instead of 2-sqrt3 it should be 2+sqrt3

[@aromlaa7066]

He corrected it at the end of the video guys

[@justintagle4019]
