According to the video solution, the answer to this question is E. However, in the grading system, D is the correct answer.
Hi Greg corrected that later on in the video.
In the video, Greg explained it correctly. However, in the test, it is still marked as the incorrect answer. Can you change the answer from D to E in the quiz as well please to avoid confusion
The answer is D, not E.
According to the video, the answer should be E. I am not sure how the answer can be 8. It will be really helpful if you can provide an explanation for the answer
See the diagram. The mistake in that is that it should have been 2\sqrt{3} - 2 - 4, not 2 - 2\sqrt{3} - 4. The height is 2, not 2\sqrt{3}.
(note: it’s a dash, not a minus sign)
Got it. Thank you for clearing the confusion
