There is a designated formula for this circle drawing. This is a secant-secant scenario, and in this case, the formula is:

CD(CD+X)=CB(CB+AB)

Plug the values in.
AB=42
BC=18
CD=4

4(4+x)=18(18+42)
Solve for x.
16+4x=1080
4x=1064
x=266
Your answer is C

The right triangle above has height h centimeters and hypotenuse t centimeters. What is the area, in square centimeters, of the
White raven [17]

Answer:

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: A = \frac{h*w}{2}

Pytagoras theorem: h^{2} + w^{2} = t^{2}

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

h^{2} + w^{2} = t^{2}

w^{2} = t^{2} - h^{2}

w = \sqrt{t^{2} - h^{2}}

So the area is:

A = \frac{h*w}{2}

A = \frac{h\sqrt{t^{2} - h^{2}}}{2}
