Option D.

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The sum of the interior angles in a triangle must be equal to 180 degrees

In this problem

substitute the values and solve for x

$(6x-6)\°+(7x+1)\°+55\°=180\°$

$13x=180\°-50\°$

$x=130\°/13=10\°$

Find the measure angle G

substitute the value of x
