Step-by-step explanation:
Answer:
24.5
Step-by-step explanation:
Since 180 is double 90 divide 45 by 2 and you'll get 24.5
Step 1: evaluate f(x+h) and f(x)
We have


And, of course,

Step 2: evaluate f(x+h)-f(x)

Step 3: evaluate (f(x+h)-f(x))/h

Step 4: evaluate the limit of step 3 as h->0

So, we have

Option D should be your answer.
No combo of any of those angles add up to exactly 180 to suggest that they are parallel lines.
