Answer:
The answer is about 1.732, the exact form being
.
Step-by-step explanation:
The square root of 12 is 3.4641. You then divide this by 2 and you get approximately 1.732. This in the exact form is
.
Since the angle are both 45 degrees, then you know that both legs are equal=12.
so to find the hypotenuse, you use the pythagorean theorem:
12^2+12^2= c^2
144+144=c^2
288=c^2
square root(144) x square root (2)=c
12 square root 2 is the answer, so D.
