Answer:
6 times the square root 2
Explanation:
Hi there!
Since this is a 45-45-90 triangle, we know the sides are a, a, and a times the square root of two.
Since we can see the 6 is on of the sides that has the 90 degree corner, we know that 6 is our a.
Therefore, we know k is the hypotenuse and is 6 times the square root 2.
Hope this helped, have a great day! ^u^
