PLEASE ANSWER THIS PLEASE I NEED HELP ASAP. I'LL GIVE THE FIRST PERSON TO ANSWER THIS BRAINLIEST! 20 Point Question! In the diagram of circle O, tangent PB is drawn as is secant PAC. We wish to prove the Secant/Tangent Length Theorem, i. e. 2 PA PC PB^2. Explain why PAB is similar to ΔPBC (i. e. explain which two angles pairs must be congruent and why). Set up a proportion involving PA, PB, PC, and based on the similar triangles and rewrite it in product form. Draw the two similar triangles separately and in the same orientation to help.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
