When incident rays of sunlight form an angle with a flat object, such as a leaf, then the intensity of sunlight is reduced by a factor of sin (0), assuming that is between 0° and 90°, as shown in the figure. factor Ө Leaf By what factor is the intensity reduced if the angle formed is 50°? (Use decimal notation. Give your answer to two decimal places.) Sunlight 0≈ Learning Crauder et al, Preparation for Calculus, 1e, 2022 Macmillan What is the angle (in degrees) 0 if the intensity is reduced by a factor of 0.6? (Use decimal notation.
