Answer:
B
Step-by-step explanation:
y=x you can imagine by drawing graph
Answer:
the first formula
Step-by-step explanation:
the graph is y=cosx and cosx=sin(x+90)
A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m (exact)
A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)
Since the equations for area is A= L*W
A= 9*4= 54
