Answer:
C) 2√3
Explanation:
This is a right triangle with one of the smaller angles = 45°
Therefore the other non-right angle = 45°
Therefore this is a right isosceles triangle with two legs equal
Each leg = √6
hypotenuse of a right isosceles triangle = √2 x a where a is each of the legs
y = √2 x √6 = √2 x √(2 x 3) = √2 x √2 x √3 = 2√3
