Best ResponseYou've already chosen the best response.0Hi Hikari  this looks quite tricky at first, but can you see how to calculate the angle marked in red? Hint: exterior angle of the smaller right angled triangle equals the angle marked in red plus 90 degrees.

Best ResponseYou've already chosen the best response.0ok back, this is a 306090 right triangle so the upper angle is 60 have you learned sin and cos functions ??

Best ResponseYou've already chosen the best response.0wait never mind, a 306090 triangle is a special triangle with ratio 1:sqrt(3):2 for our triangle 9:9sqrt(3):18 therefore k + 3sqrt(3) = 9sqrt(3) k = 6sqrt(3)

Best ResponseYou've already chosen the best response.0a 306090 triangle is a special triangle with ratio 1:sqrt(3):2 for our triangle 9:9sqrt(3):18 therefore k + 3sqrt(3) = 9sqrt(3) k = 6sqrt(3) sqrt = square root why are you multiplying 3*3*3 and 9*9*9

Best ResponseYou've already chosen the best response.01:sqrt(3):2 means vertical side length is 1 bottom side length is sqrt(3) hypotenuse or diagonal side is 2 because for our triangle the vertical side is 9 9 is our scale factor multiply everything by 9 9:9sq3:18 bottom side is 9sq3 diagonal is 18
