Is there more to this question or no?
I think the answer will be 17 square that what my friend said.
Using cos addition formula:
use x for theta
cos(x+π/6)=cosx*cos(π/6)-sinx*sin(π/6)
sinx=1/4
cosx=√15/4
cos(π/6)=√3/2
sin(π/6)=1/2
cos(x+π/6)=(√15/4*√3/2)-(1/4*1/2)
cos(x+π/6)=(√45/8)-(1/8 )
cos(x+π/6)=(√45-1)/8)
Answer:
The length of each edge of the cube is 1 unit.
Step-by-step explanation:
Volume of the cube = x * x * x = x^3
So x^3 = 1
x = 1.
