Answer:

B. 25

Explanation:

We can use the altitude theorem, to quickly find the value of x.

According to this theorem; the altitude of the triangle is equal to the geometric mean of the product of the two segments created by the leg of the altitude on the hypotenuse.

We apply this theorem to obtain:


10=√(4x)

This implies that:


10^2=4x


100=4x

Divide both sides by 4 to obtain:


(100)/(4)=x


x=25
