Finding the missing values and show all your work on how you got the answers.

a) Given triangle is a right angle triangle

So we use trigonometric properties

y = sin(51) * 12

y= 9.3257515

y= 9.33

b) It is a right angle triangle

sin(theta) = opposite / hypotenuse

sin ( theta) =

theta =

theta = 67.38 degree

c)

x= 29.238044

Hypotenuse x= 29.24

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.
