Question

PLEASE ANSWER + BRAINLIEST!!

Answer 1

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:

$a^2=x^2+h^2$

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

$h^2=a^2-x^2$

Answer 2

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.
