Confused on question in screenshot

4 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

3^2 + (sqrt(39)^2 = c^2

9 + 39 = c^2

48 = c^2

Take the square root of each side

sqrt(48) = sqrt(c^2)

sqrt(16*3) = c

sqrt(16) sqrt(3) = c

4 sqrt(3) = c

what are the options? ?
