Use the quadratic formula to find all degree solutions and θ if 0° ≤ θ < 360°. Use a calculator to approximate all answers to the nearest tenth of a degree. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.) cos2 θ + cos θ − 1 = 0 (a) all degree solutions (Let k be any integer.) θ = (b) 0° ≤ θ < 360° θ =
