Given that the hyperbola has a center at (0,0), and its vertices and foci are on y-axis. This, the equation of the hyperbola is of the form x²/a²-y²/b²=-1 (a>0, b>0) In the equation, vertices are (0, +/-b) . Thus, b=60 Foci (0,+/-√(a²+b²)) thus √(a²+60²)=65 hence solving for a² a²=65²-60² a²=625 a²=25² hence the equation is: x²/25²-y²/60²=-1
