The angles opposite equal sides are also equal. The sum of angles in a triangle is 180. So 2x + 27 + 2x + 27 + 3x + 28 = 180.

7x + 82 = 180
7x = 98
x = 14

Now plug x into each angle to find their measures.

C. X = 16

To solve, add 7 to both sides and multiply by the reciprocal of $\frac{-9}{8}$ , $\frac{-8}{9}$ .

$( \frac{-9}{8} ) X - 7 = -25


$
$( \frac{-9}{8} ) X = -18$
$X = 16$
