Question 457705
In a right triangle, find the length of the side not given. Approximate to three decimals, if necessary. Keep in mind that a and b are the lengths of the legs and c is the length of the hypotenuse. 
b=4√2, c=9
-----------------------------
a = sqrt[(9^2 - 4sqrt(2))^2 ]
---
a = sqrt[81 - 32]
----
a = sqrt(49)]
a = 7
