The inverse operation of subtraction is addition. Lets use the inverse operation to solve x. Lets do it:-
x - 5.6 = -1.7
-1.7 + 5.6 = x
-1.7 + 5.6 = 3.9
x = 3.9
CHECK OUR WORK:-
3.9 - 5.6 = -1.7
We were RIGHT!!
So, x = 3.9.
Hope I helped ya!!

Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
