Which equation gives the length of the altitude of ABC?

B. AD = sqrt(CD * BD)

Step-by-step explanation:

By the right triangle altitude theorem,

CD/AD = AD/BD

AD^2 = CD * BD

AD = sqrt(CD * BD)

B. AD = sqrt(CD * BD)

B

Step-by-step explanation:

In this question, you are clearly supposed to use the geometric mean theorem or known as the right triangle altitude theorem. But note that there are other approaches to find the height of the triangle.

Using Pythagorean theorem:

Also,

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
