To determine the value of x, we need more information. The measures of angles alone cannot determine the value of x without additional angles or side lengths.

the image shows two lines that intersect, an angle on one side is 8x-8 degrees, and the equal but opposite side is 5x+11, both of these angles are obtuse, use this information to help answer the question

welp I tried, thanks for the help
The property of equality that justifies the statement "m + 4 = 18" is the Substitution Property.
To understand why, we need to look at the given information:
1. "m + n = 18" and
2. "n = 4".
By the Substitution Property, we can replace the variable "n" in the first equation with its given value of 4.
So, substitute n = 4 into the equation "m + n = 18":
m + 4 = 18.
Therefore, the Substitution Property allows us to replace a variable with its given value in an equation.
