A = b*h/2, A = 5x * 3x / 2 = 67.5, Multiply both sides by 2: 5x * 3x = 135, 15x^2 = 135, x^2 = 9, X = 3. b = 5x = 5*3 = 15. h = 3x = 3*3 = 9.

Are you more comfortable thinking in degrees? -3π/4 radians = -135° ( clockwise) -135 is coterminal with +225° so we could write our point as (-1,225°) which is the same as (+1 , +45°) so x = cos45/1 = √2/2 y = sin45/1 = √2/2 the point is (√2/2,√2/2)
