Answer:

x = sqrt(96)

x = 4 sqrt(6)

Explanation:

We can use the Pythagorean theorem to find x since this is a right triangle

The base would be 5 1/2 of the full length of 10

The hypotenuse would be 11

a^2 + b^2 = c^2

5^2 + x^2 = 11^2

25 + x^2 = 121

Subtract 25 from each side

25-25 + x^2 = 121-25

x^2 =96

Take the square root of each side

sqrt(x^2) = sqrt(96)

x = sqrt(96)

x = sqrt(16*6)

We know sqrt(a*b) = sqrt(a) sqrt(b)

x =sqrt(16) sqrt(6)

x = 4 sqrt(6)
