For pictures 3 and 4 make sure to review related angles.
make sure to remember the unit circle definitions of trigonometric functions.
sin theta = y
cos theta = x
tan theta = y/x
How can you use these definitions to answers questions 3/4
The answers given in picture 4 c/d is incorrect.
Using identities like sin^2 theta + cos^2 theta = 1 7, 9, 10
You can find a list of trigonometric identities on khan academy all you got do is apply them
