The plane 2x-3y+6z-11=0 makes an angle sin-1α with x-axis. The value

1.	The plane 2x-3y+6z-11=0 makes an angle sin-1α with x-axis. The value of α is equal to(a) 32(b) 23(c) 27(d) 37
Answer» The plane 2x-3y+6z-11=0 makes an angle $\sin^{- 1} α$ with x-axis. The value of $α$ is equal to (a) $\frac{\sqrt{3}}{2}$ (b) $\frac{\sqrt{2}}{3}$ (c) $\frac{2}{7}$ (d) $\frac{3}{7}$
