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

51-50

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
