							Ans:Steps:
First, you write the equation of tangent in slope form for both the ellipse & hyperbola.
Then you just equate the constant since both equation represent same tangent.
Then, tou would get an polynomial equation in slope.
You find the individual slopes & calcute the angle b/w them by using the formula
$tan\alpha = |\frac{m_{1}-m_{2}}{1+m_{1}m_{2}}|$Thanks & RegardsJitender SinghIIT DelhiaskIITians Faculty
