Best ResponseYou've already chosen the best response.2in the regular octagon.there will be 8 equilateral triangle hence let the side is x. then area of octagon=8*area of one equilateral triangle =\[8\times \sqrt{3}\div 4 (x ^{2})\]..find x.

Best ResponseYou've already chosen the best response.2tan67.5=x let dw:1334306229613:dw x=root2+1 is only possible because 67.5 is in first quadrant and in first quadrant tan ins positive.hence neglect negative value(1root2)
