How do i even do this? i'm so beyond confused.

Step-by-step explanation:

1. Know that a triangle is 180 degrees.

2. Do 180 - 100 = 80 degrees, so angle A and T both equal 80

3. Draw Isosceles to see how the angles should look then solve for x.

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.
