Answer:

x coordinate is negative

y coordinate is positive

Step-by-step explanation:

We know that

$\pi=180$

Hence

$\frac{3\pi}{4}=\frac{3*180}{4}$

$\frac{3\pi}{4}=3*45=135$

Hence our angle lies in the second quadrant. Second quadrant is enclosed by the negative x axis and positive y axis.

In second quadrant, we have negative value if x coordinate and positive value of y coordinate.

3pi/4 is 135 in degrees. A 135-degree angle lies in quadrant 2. In quadrant 2, the x values are negative and the y values are positive.
