Answer:

Explanation:
We can solve for j by using our knowledge of 45-45-90 triangles.
• the legs are congruent
• the hypotenuse is
times the length of the legs
We can use that second fact to solve for j. Since j is a leg, we can divide the hypotenuse (22 km) by
to solve for it.

Now, we can rationalize j by multiplying by
.
