Find the measure of AB¯¯¯¯¯¯¯¯. A. 14 B. 22 C. 21 D. 20

C. 21

Step-by-step explanation:

We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:

BC * AC = DC * EC

Here:

AC = AB + BC = (2x + 5) + 9 = 2x + 14

BC = 9

DC = 10

EC = KC = (1 + 2x) + 10 = 2x + 11

So plug all these in:

BC * AC = DC * EC

9 * (2x + 14) = 10 * (2x + 11)

18x + 126 = 20x + 110

2x = 126 - 110 = 16

x = 8

Put this back into the expression for AB:

AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21

The answer is thus C.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
