Answer:
6√2
Step-by-step explanation:
A 45 45 90 right triangle, so ratio of leg : leg: hypotenuse = a: a : a√2 (a = value of leg)
Given: leg = 6
So the ratio of leg : leg: hypotenuse = 6 : 6 : 6 √2
Answer:
x = 6√2
We know that 15 elves represent the 20% of the total.
Since 20% is one-fifth, the total number of elves is

Alternatively, solve the proportion
