Q) Two sloping roof structures must be constructed at an angle of 60°. The roof structures can be modelled as planes given by the equations
x+2y+2z=5
ax+y+z=2
Find the exact value of a.
I'm not sure how to do this question. I tried using the dot product of the direction vectors (1,2,2) and (a,1,1) but ended up with a polynomial that lacked real roots. Any help would be appreciated
