Find the reference angle for 342°. 1) 35°2) 5°3) 18°4) 162°

Sagot :

For an angle a in the fourth quadrant, the reference angle is given by:

360º - a

The angles in the fourth quadrant are those between 270º and 360º. So, 342º is in the fourth quadrant, and its reference angle is:

360º - 342º = 18º

Therefore, the third option is correct.
