Do you know how to solve a simple equation?
Assuming that you do, everything is basically the same.
For example 1,
you take the sin inverse of 3/4 and solve for (x + pi/2) as you normally would for x
when you have found the angles using quadrant rule/graph just subtract pi/2 in the end from those angles
thats it.
Simple rule: When you have something with x in bracket, leave it as it is and only in the end subtract/add or whatever.
for example 4 in the file, you have to write all the terms in the same trig. function.
some examples here: http://www.examsolutions.co.uk/maths-revision/core-maths/trigonometry/equations/squared-types/example-1.php
if you still have a problem then let me know :D
