Question

SOMEONE PLS HELP PRECALCULUS

Answer 1

Sine is negative in quadrants 3 and 4, when y < 0.

Tangent is negative for quadrants 2 and 4, when y/x < 0. Basically when x and y differ in sign (one is positive, the other is negative)

The common quadrant mentioned is quadrant 4.

Quadrant 4 has angles that are between 270 degrees and 360 degrees

So we have
`270^(\circ) < \theta < 360^(\circ)`

Answer: Choice D
