correct answer, thanks for 15 pts
Half of pi/3 means 1/2 times pi/3=pi/6
The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is
A = 0.5bh
The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:
4A = 33
Substituting A = 0.5*5.5*h = 2.75h to the equation:
4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet
Answer:
37°
Step-by-step explanation:
∠ECF= ∠ACG
∠ACG= 90° - ∠GAC= 90° - 53°= 37°
