I prefer to give you hints and if you can't solve it ask for help
for the first question
since the same thing for
now you have a=1 and you have sin(b) now to find the value of
since a=1
use
the second question
first thing you should know
you can write the angle
then use the formula
5)
You should have recognized the ratios (the alternate form is ).
Ask yourself, the sine of what angles is ? (There are two answers). Then ask yourself, the sine of what angles is ? (There are two more answers). If you have to, draw some triangles in the cartesian plane.
