In which quadrant is this point (-3,-7) a. quadrant i b. quadrant ii c. quadrant iii d. quadrant iv

C - Quadrant III

Step-by-step explanation:

This is because if you look at a graph, you can first sketch out each quadrant.

Quadrant I is typically the quadrant in which students are usually in; it's where both numbers are positive. On the unit circle, it'd the degrees of 0-90.

Quadrant II is the one to the left of Quadrant I - it's where the x's are typically negative and the y's are positive. On the unit circle, it'd be 90-180.

Quadrant III is where both numbers are negative, such as the point provided. On the unit circle, this is typically 180-270.

Quadrant IV is the same as Quadrant II, except the x is positive and the y is negative. This is where it's 270-360 degrees on the unit circle.

With the provided definitions of each quadrant, it can be determined that the point -3, -7 is in quadrant III.

Hope this helps!

C

Step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
