How do you find the length of the missing side of a right triangle if the hypotenuse is 4sqrt3 and the short side is 2?

I found the length as 6.6

Explanation:

I would use Pythagora's Theorem as:
c^2=a^2+b^2
where c=4sqrt(3) is the hipotenuse.
So:
16*3=4+b^2
b=sqrt(48-4)=6.6

The length of the missing side is exactly 2sqrt11.

Explanation:

Use the Pythagorean theorem c^2=a^2+b^2, where c is the hypotenuse of a right triangle, and a and b are sides or legs of the right triangle.

For this question:

c=4sqrt3
a=2
b=?

Solve the Pythagorean theorem for a.

b^2=c^2-a^2

b^2=(4sqrt3)^2-2^2 =

b^2=16(3)-4 =

b^2=48-4=44

b=sqrt44 =

b=sqrt(4xx11) =

b=2sqrt11
