Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
Answer:
10/4 is the amount it takes
Step-by-step explanation:
Area of the Base = 6 * side^2 / 4 * tan (180/6)Area of the Base = 6 * 16 / 4 * 0.57735Area of the Base = 96 / 2.3094 Area of the Base = 41.5692387633
Area of 1 Face = 2 * 6 = 12Area of 6 Faces = 72
Total Area = 41.5692387633 + 72Total Area = 113.5692387633
