some body help me i am under the water

Answer:
sqrt(29)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + 5^2 = ?^2
4+25 = ?^2
29 = ?^2
Taking the square root of each side
sqrt(29) = sqrt(/^2)
sqrt(29) = ?
