Answer:
n= -4/7
Step-by-step explanation:
13 3/4 = ((13x4)+3)/4 = 55/4
1 2/3 = ((1x3)+2)/3 = 5/3
55/4 / 5/3
(55x3)/(5x4)
165/20
33/4
8 1/4
Answer:
<em>1. B.</em>
<em>2. B.</em>
Step-by-step explanation:
<u>Trigonometry</u>
1) Coterminal angles can be found by adding or subtracting 360° (or 2\pi radians) to a given angle. If we have 120°, adding 360° gives 480°, adding again 360° gives 840°. There is no way to get -180°, so this option is not a coterminal angle to 120°
2)
A.
, and not undefined
B.
. This is correct
C.
is undefined, not zero
Thus the only correct option is B.
