Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... the line y = x is the point (y, x). The reflection of the point (x,y) across. the line y = -x is the point (-y, -x).
Step-by-step explanation:
we know that
Two angles are Complementary when they add up to 
degrees and two angles are Supplementary when they add up to 
degrees
f the exterior sides are opposite rays, then a straight line forms and you have the two angles add to degrees
So
the angles are supplementary and not complementary
therefore
the answer is the option
Never
Answer:
an-1-9
25n-1-9
25n-10=0
25n=0+10
25n=10
divide both sides by 25
25n/25 =10/25
n=2/5
