5. in which quadrant does the terminal side of al 18° angle lie?
a. third quadrant
c. first quadrant
b. second quadrant
d. fourth quadrant

first quadrant

Step-by-step explanation:

the angle of 18° lies at the first quadrant since this one includes the ranges of angles  between 0 and 90°

Going south means you're going in the negative direction along the y axis

Going 4 yards south would be represented as -4 on the y axis number line (this is the vertical number line)
