Using Pythagoras' theorem (a² + b² = c²), the correct answer is:

D. h² = a² - x²

Because a would be the hypotenuse, but h is not, so you have to rearrange the equation.

Answer:

The answer is D

Step-by-step explanation:

BCD is a right triangle. On BCD triangle hypotenuse theorem can be applied. From the hypotenuse  theorem below equation can be written:

[tex]a^2=x^2+h^2[/tex]

If we change the side of x the equation will be:

[tex]h^2=a^2-x^2[/tex]
