  1. cos(t) = 1.5/3 = 1/2
    t = π/3 or 60°

    Better review you standard 30-60-90 and 45-45-90 triangles. They pop up often.

    determine the vertex for the function y=2x^2+5x-3 for y = ax^2 + bx + c, the x value of the vertex is -b/(2a) sub that x into your equation to find the y. Another way is to complete the square. so for yours, x = -5/4 etc. a third
