List all of the integer values of x that are part of the solution set for the following inequality: −7 < x ≤ −5

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.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

How do i do this? i don’t understand
