Answer:

A

Explanation:

This is a right triangle, because of the little square in the corner that represents a right angle.

Therefore, the Pythagorean Theorem can be used.

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse

In this triangle, 2 and 10 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.

2 and 10 are a and b, and x is c.

2^2+10^2=x^2

Evaluate the exponents on the left side.

4+100=x^2

104=x^2

x is being squared. To reverse this, take the square root of both sides

√104=√x^2

√104=x

A, x=√104 is correct
