If m∠4 = 100°, what is m∠5?

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

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)
