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
Answer:
Step-by-step explanation:
![2a(5a^7)\\ \\ 2(5)a(a^7)\\ \\ 10a^{(1+7)}\\ \\ 10a^8](https://tex.z-dn.net/?f=2a%285a%5E7%29%5C%5C%20%5C%5C%202%285%29a%28a%5E7%29%5C%5C%20%5C%5C%2010a%5E%7B%281%2B7%29%7D%5C%5C%20%5C%5C%2010a%5E8)
32 + 46 + 39 = $117 ( total cost)
117 / 3 = $39 ( average price)
This is 6^2 + 5(6) - (4^2 + 5(4)) (66 - 36) / 2 =15 answer
