Answer:

A

Explanation:

The segment from the vertex to the base , bisects the base at right angles

Then there are 2 right triangles with legs x and 4 and hypotenuse
√(52)

Using Pythagoras' identity in either of the 2 right angles

x² + 4² = (
√(52)

x² + 16= 52 ( subtract 16 from both sides )

x² = 36 ( take the square root of both sides )

x =
√(36) = 6 → A
