Solve for x.
A. x = √55
B. x = √73
C. x = 4√7
D. x = √130

C. x = 4√7

Step-by-step explanation:

This is a right triangle

The hypotenuse is 3+8  (the radius is 3 and the exterior length is 8)

We can use the Pythagorean theorem

a^2 +b^2 = c^2

3^2 + x^2 = 11^2

9+x^2 = 121

Subtract 9 from each side

9-9 + x^2 = 121-9

x^2 = 112

Take the square root of each side

sqrt(x^2) = sqrt(112)

x = sqrt(16*7)

x = 4 sqrt(7)
