Answer:
Mickey
Step-by-step explanation:
Mickey is correct because if you look at the number 45.7654 whenever you round to the nearest thousandth it'll be 45.765
5 is the thousandth place so look to the right. If the number to the right is greater than 5 it'll round to 47.766 but since it's a four ti rounds down.
In a 45-45-90 triangle, both of the legs have the same length and the ratio of one leg to the hypotenuse is 1:sqrt(2).
