I need help with this, I don’t understand how to do this.

x = 94

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360

49+128+89+x = 360

Combine like terms

266 +x = 360

Subtract 266 from each side

266-266+x = 360-266

x =94

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
