    The definition of bisecting an angle means that you are dividing the angle in half. So set these two angles equal to each other and solve for x.

    7 x + 9 = 3 x + 17

    4 x = 8

    x = 2

    since EG is the bisector both angles are equal

    7x + 9 = 3x +17

    7x - 3x= 17- 9

    4x = 8

    x = 2
