James wants to cover a floor measuring 90cm by 20cm with square tiles of the same size. Given that he uses only whole tiles, find; a) The largest possible length of the side of each tile? b) The number of tiles that are needed to cover the floor?

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
