Step-by-step explanation:
Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25
we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound
if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5
so the product of any 2 numbers between 4 and 5 will be between 16 and 25
so pick any random one
4 and 3/4 times 4 and 5/323
Total units of ratio = 2+4+4 = 10
value of 1 unit = 180/10 = 18
angles would be: 2(18), 4(18), 4(18) = 36, 72 & 72
