Answer:
x=11 degrees
Step-by-step explanation:
There's a property of a triangle where the sum of two of the interior angles is equal to 180-(last interior angle). In this case, 180-(last interior angle) is equal to 7x-1, because angles BAE and BAC are supplementary, which means that they add up to 180 degrees.
So, we can set up an equation
(56)+(2x-2)=(7x-1)
Solving, we get
56+2x-2=7x-1
56-2=5x-1
54+1=5x
55=5x
11=x
