Answer:

m<S=66.5

Step-by-step explanation:

The sum of the angles = 360

(6x-6)+(4x-10)+(5x-11)+(5x+13)+(4x+2) = 360

24x-12=360

24x=372

x=15.5

S=5x-11 = 5*15.5-11=66.5

Answer:

104

we have:

6x - 6 + 4x - 10 + 5x - 11 + 5x + 13 + 4x + 2 = 180.3

<=> 24x - 12 = 540

<=> 24x = 552

<=> x = 552/24

<=> x = 23

with x = 23, we have: m<S = 5.23 - 11 = 115 - 11 = 104
