Question

Please help me with this problem

Answer 1

Answer:

½

Explanation:

According to the Unit Circle, tan 240° [when it falls in between 180° and 270°] is √3, so we plug this into the sine function to get this:

sin 240° - 210° → sin 30° >> ½

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.

**** Now, 60° is the main possible answer, however, it falls in between 0° and 90°, not 180° and 270°.
