So if 2 notebooks cost 12 divide that
12/2 =6 $ each
So to check if its true the 3notebooksx $6 dollars each should =$18 for 3 notebooks
5 notebooks at $6 each = $30 for 5 notebooks
so What is 4notebooks x$6 each ? =4x6 = $24 for 4 notebooks
On the unit circle the hypotenuse is always one so we can say:
sinα=y/1 and cosα=x/1 so
The point corresponding the the angle 600° is:
(cos600, sin600) which is approximately
(-1/2, -√(3/4)
The answer is D because both of those answer choices can be proved by looking at the triangle
Answer:
Both are Obtuse Angles
