What is the length of the segment with endpoints (-3,4) and (5,4)?

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

This is so hard and it’s for a test
