A flag is hung 22 meters up a flagpole. As the flag is raised, the angle of elevation from point 21 meters away from the base of the of the flagpole to the flag is 74 degrees. Find the increase in height of the flag.

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8
