=81x2+45x−45x−25

=81x2−25

An angle whose measure is –302° is in standard position. In which quadrant does the terminal side of the angle fall?

juin [17]

Answer: Quadrant 1 (northeast quadrant)

=================================================

Explanation:

Add on 360 degrees to do a full rotation

-302+360 = 58

So angles -302 degrees and 58 degrees are pointing in the same direction. These angles are in quadrant 1, which is the northeast quadrant

Note: because the angles -302 and 58 point in the same direction, we consider these angles to be coterminal.
