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.
Answer:
Step-by-step explanation:
Your answer is:
(125 - 8x^3) / (25 + 10x + 4x^2) = - ((2x - 5) * (4x^2 + 10x + 25)) / (4x^2 + 10x + 25) = - (2x - 5) = - 2x + 5
The correct result would be - 2x + 5.
