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
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
