Pl = 10 pk = 8 l is a point of tangency. the segments pl and pn have a common point at p. find the length kn. a) 4 b) 4.5 c) 5 d) 5.5
B is the answer to this question
Lol the answer is B) 4.5 Walkthrough: JUST TAKE USATESTPREP ↓ PK*PN = PL2. Let PN = x. 8x = 102 and x = 12.5. KN = PN – PK. 12.5 – 8 = 4.5. ♥♥¯_(ツ)_/¯♥♥
8x = 100 x = 100/8 x = 12.5KN = PN – PK 12.5 – 8 = 4.5 would be the length of the KN segment.
The answer to the question is 4.5.
