Answer:

use Pythagoras theorem

the missing side is base

Step-by-step explanation:

pythagoras theorem

h^2 = p^2 + b^2

1. Find the vertices and locate the foci for the hyperbola whose equation is given.
Irina18 [472]
\bf \cfrac{(x-{{ h}})^2}{{{ a}}^2}-\cfrac{(y-{{ k}})^2}{{{ b}}^2}=1&#10;\qquad center\ ({{ h}},{{ k}})\qquad&#10; vertices\ ({{ h}}\pm a, {{ k}})\\\\&#10;-----------------------------\\\\&#10;\textit{now let's take a look at yours}&#10;\\\\\\&#10;49x2 - 16y2 = 784\implies \cfrac{49x^2}{784}-\cfrac{16y^2}{784}=1&#10;\\\\\\&#10;\cfrac{x^2}{16}-\cfrac{y^2}{49}=1\implies \cfrac{(x-0)^2}{4^2}-\cfrac{(y-0)^2}{7^2}=1&#10;\\\\\\&#10;recall\implies center\ ({{ h}},{{ k}})\qquad vertices\ ({{ h}}\pm a, {{ k}})&#10;\\\\\\&#10;

\bf \textit{now, for the foci, the foci are "c" distance from the center point}\\\\\&#10;whereas\qquad c=\sqrt{a^2+b^2}\qquad \textit{ that is }\qquad  h\pm \sqrt{a^2+b^2}

notice your "a" and "b" components, to get the distance "c" from the center to either foci and the vertices, of course, are h + a, k and h - a, k
