Because both lines DE and XY are parallel to one another, the 115° will be same for the line segment. XY
And because XY is a flat line, it's a straight angle. Meaning it's an 180° angle.
We need to find a value of x that when added 115° will equal 180°.
We can use this equation: x + 115 = 180
Subtract both sides 115.
x + 115 - 115 = 180 - 115
x = 65
So, x is equal to 65 degrees.

Step-by-step explanation:
As you know this graph is a lemniscate

X = log (base b) y
The base of the log becomes the base of the exponent.
The x and y switch.
b^x = y
