Tan= 34/x. Angle is 27°

x = 17.3238

Step-by-step explanation:

Tan Ф = 34/x

cross multiply,

x = 34×Tan Ф

but, Ф = 27°

so that, x =34 × Tan 27°

x = 17.3238

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.
