Help! Find m^KNL.<br> A. 264<br> B. 196<br> C. 184<br> D. 247
Misha Larkins [42]

Answer:

  A.  264

Step-by-step explanation:

First, we have to find the value of x. Then we can use that to find the required arc measure.

∠M = (1/2)(arc KN - arc LN)

60 = (1/2)((18x -6) -(5x +17)) = (1/2)(13x -23) . . . . substitute and simplify

120 = 13x -23 . . . . . . . multiply by 2

143 = 13x . . . . . . . . . . add 23

11 = x . . . . . . . . . . . . . . divide by 13

__

arc KNL = (arc KN) + (arc NL) = (18x -6) +(5x +17) = 23x +11

  = 23·11 +11

arc KNL = 264 . . . . degrees
