First-degree trigonometric equations help

In these questions, find, to the nearest degree, the positive acute angle(s) that satisfy the equation.


1) tan^2x - 4tanx + 3 = 0


2) tan^2x - 2tanx = 3


3) 6sin^2x - 5sinx + 1 = 0

tanx=3 => tan inverse (3) = 71.56 , => x=71.56. (you could use scientific calculator to find tan inverse of 3 value) I have only given integer values earlier. So, the total range of values also include, tanx = 1 (45 degrees (1st Quadrant), 225 degrees (3rd Quadrant)) and tanx=3 (71.56 degrees (1st Quadrant), 251.56 degrees (3rd Quadrant)) )

Since the tan value generally is positive in 1st and 3rd quadrants and in this case 1 and 3 are positives. So, we find x value for both the quadrants.
