Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Which graph represents the given linear function 4x+2y=3

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
