This is so hard need i think its b.. confirmation?

22sqrt(3)/3

You are correct.

Step-by-step explanation:

You have a 30-60-90 triangle.

In a 30-60-90 triangle, the hypotenuse is twice the length of the short leg. The long leg is sqrt(3) times the length of the short leg.

You are given the length of the long leg.

1) Find the length of the short leg.

HG = GI/sqrt(3) = 11/sqrt(3)

2) Find the length of the hypotenuse, HI.

HI = 2HG = 2(11/sqrt(3)) = 2(11/sqrt(3))*(sqrt(3))/(sqrt(3)) = 22sqrt(3)/3

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
