Answer:

Step-by-step explanation:
We want to simplify:

Recall the Pythagorean Identity:

So:

Substitute:

Factor. We can use the difference of two squares pattern:

Cancel. Hence:

Answer:
y=9
Step-by-step explanation:
y=mx+c
gradient of a horizontal line is 0
y=0x+9
y=9
Answer:
A, B, C, and D, all options are correct.
A is correct because,
∠2 and ∠3 are corresponding angles.
B is correct because,
∠5 and ∠7 are corresponding angles.
C is correct because,
∠2 and ∠4 are corresponding angles.
D is correct because,
∠5 and ∠6 are alternate interior angles.
Note,
If two lines parallel, then
- Corresponding angles are equal.
- Alternate interior angles are equal.
