Answer:(b), (c)
Step-by-step explanation:
Given angle is [tex]=\frac{3\pi }{4}[/tex]
Coterminal angles are those which shares same staring side and terminating side
The coterminal of given angle is
[tex]\Rightarrow \frac{3\pi }{4}+2\pi =\frac{11\pi }{4}[/tex]
Negative coterminal angle
[tex]\Rightarrow \frac{3\pi }{4}-2\pi [/tex]
[tex]\Rightarrow -\frac{5\pi }{4}[/tex]
Thus option (b) and (c) are correct
