C) Adjacent angles whose exterior sides are perpendicular rays are complementary.
Complementary = add up to 90
Supplementary = add up to 180
Perpendicular because the slopes are different and on is negative and the other positive.
Answer:
at least 17
Step-by-step explanation:
if you add and shid it kinda like division multiplied by 10. ya know
Answer:
1 ÷ 2(9 + x)
4.5 + 0.5x
Step-by-step explanation:
Given that
We write the expression i.e. half of the sum of $9 and a number
Here we need to write the two expression that is different from each other
So,
Let us assume the number be x.
Now The first equation depend on the information given will be:
= 1 ÷ 2(9 + x)
And, The second equation is
= (9 + x) ÷ 2
= 4.5 + 0.5x
