Solve the following problems. Show your complete solution. Box final answers. OBSERVE TIME LIMIT. 1. The line segment joining (-5, -3) and (3,4) is to be divided into five equal parts. Find the point of division closest to (-5, -3). 2. In what ratio does the x - axis divide the segment joining (-5,4) and (4, -8)? 3. Find the interior angles of the triangle A(5,4), B(-1,1), and C(3, -2). Round off to two decimal places if needed. 4. A line with an angle of inclination of 45 passes through ( -5, -2) . If the ordinate of the point is 6, what is its abscissa? 5. The three vertices of a triangle are at A(-4,5), B(-5,3), and C(3, -4). Show that the line joining the midpoints of the sides AC and BC is parallel and equal to one-half of AB
