### Instruction: help me answer this question Vertices (0, ± 13), foci (0, ± 5), think step by step
### Assistant: The vertices and foci given are on the y-axis, so the equation will be of the form x2/b2 + y2/a2 = 1. Here, a = 13, c = 5. Using a2 = b2 + c2, b2 = 169 – 15 = 144. So, the equation of the ellipse is x2/144 + y2/169 = 1. , The answer is The equation of the ellipse is x2/144 + y2/169 = 1
