In Triangle EFG,9 = 12 inches, e = 55 inches and Angle F=75º. Find the area of Triangle EFG, to the nearest square inch.

9514 1404 393

  319 in²

Step-by-step explanation:

The applicable area formula is ...

  A = 1/2(g)(e)·sin(F)

  A = 1/2·(12 in)(55 in)sin(75°) ≈ 319 in²

The area of the triangle is about 319 square inches.

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.
