I just guessed and it is 108
Answer: Angle CDG, I think.
Step-by-step explanation:
The definition of Corresponding Angle is: On the same side of the transversal. One is interior and the other is exterior.
Since ADE is interior, then the other angle must be exterior.
This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.
a = -3
b = -4
c = -4
x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) =
<em>2 + √-32/2</em>x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =
<em> 2 - √-32/2</em>
