Answer:
18 square units.
Step-by-step explanation:
Answer:
I believe the answer is 184.
Step-by-step explanation:
When finding the Volume and the question has 2/3 key words, (length, width height) , it usually means you solve the question by multiplying everything together. (2 x 23 x 4) = 184.
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)
