If F1 and F2 are the two focal points of hyperbola x ^ 2 / 9-y ^ 2 / 16 = 1, if the distance between a point m on the hyperbola and one of its focal points is equal to 16, find the distance between the other focal point

If F1 and F2 are the two focal points of hyperbola x ^ 2 / 9-y ^ 2 / 16 = 1, if the distance between a point m on the hyperbola and one of its focal points is equal to 16, find the distance between the other focal point

Hyperbola x ^ 2 / 9-y ^ 2 / 16 = 1
Focus F1 (- 5,0), F2 (5,0)
If | MF1 | = 16,
When m is on the left branch,
|MF2|-|MF1|=2a=6
∴|MF2|=16+6=22
When m is on the right branch,
|MF1|-|MF2|=6
∴|MF2|=|MF1|-6=10
That is, the distance from m to another focus is 22 or 10
