There is no work. i just did it in my head. x = 15 because 15^2 equals 225 and 15+2 = 17 so if 15*15 equals 225 then if you add 30 more that is 255. 30 is equal 2*15 and so you could also say 15*15+(15*2) so 15*17 = 255 so x = 15. you're welcome.
if the number of times spun is not a multiple of 8, it is impossible to land on an exactly even distribution for this spinner. But since the probabilities of landing on an exactly even distribution are so small, that detail doesn't perturb the overall trend, except perhaps down at n=8 spins So group 3
There are two congruent triangles that are being formed from the lamppost, the light, the ground and the man. Always try to draw a picture for these types of problems. It helps a lot when solving. Your answer should be about 4.3ft
