Hello, I am a bit confused on this question. Greg has told us previously that only four of the triplets were necessary to memorize, but this question involves knowledge of a triplet that is not part of that list of four. Are we actually supposed to know more triplets than just the four, or should we simply have the triplets formula memorized? Or was the intention of this problem to instead solve with algebra? Thanks!
Divide by 10.
Giving us 21 and 7, and then are you suggesting just plugging in values? Of course, the values we’d have to choose would be decimals rather than integers here.
OK sorry I misread the problem. This question is not well-formatted actually (it should read “right-angled triangle” instead of a triplet) - where did you see it?
This was hard fundamentals quiz #1, question 10.
The question has been adjusted - check now.
