distance of vertices from center = 34/2 = 17
distance of co-vertices from center = 16/2 = 8
distance of focus from center = √(17²-8²) = √225 = 15
distance between foci = 2×15 = 30
distance of co-vertices from center = 16/2 = 8
distance of focus from center = √(17²-8²) = √225 = 15
distance between foci = 2×15 = 30

center-to-focus distance
= sqrt(17^2 - 8^2) = 15;
distance between foci = 2*15 = 30.
= sqrt(17^2 - 8^2) = 15;
distance between foci = 2*15 = 30.
