Answer 1

Answer:(b), (c)

Step-by-step explanation:

Given angle is $=\frac{3\pi }{4}$

Coterminal angles are those which shares same staring side and terminating side

The coterminal of given angle is

$\Rightarrow \frac{3\pi }{4}+2\pi =\frac{11\pi }{4}$

Negative coterminal angle

$\Rightarrow \frac{3\pi }{4}-2\pi$

$\Rightarrow -\frac{5\pi }{4}$

Thus option (b) and (c) are correct
