    Use magic, the right spell to conure the answer is, “triangles and angels, summon the angel, with halo fair, put the answer there. Bree aye fair, Griff on grap, Preab ay bar, go on graph” this is the spell that will give you the answer.

    I think it’s D. 3

    Pythagorus theorem for right angled triangle   

    the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle. So 3x root 2 squared =18

    And 3 squared = 9 x 2. = 18
