Solution:
Draw the two legs of the right triangle (Refer to image). According to the image, point R shows a right angle. This means that:
- Line JR = 5 units
- Line RK = 9 units
Now, let's use Pythagoras theorem to find JK.
- JK² = 5² + 9²
- => JK² = 25 + 81
- => JK² = 106
- => JK = √106 (Option A)
Option A is correct.
