1. Let θ be an angle in standard position with terminal side not lying on the x- or y-axis. The reference angle for θ is the acute angle θ0 (0° < θ0 < 90°) formed by the terminal side of θ and the x-axis. For example, if θ = 150° then θ0 = 30°, or if θ = 5π/3 then θ0 = π/3. Find the reference angle for each angle. (a) 7π/6 (b) −135° (c) 120°
