Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are . * 2 points
Equal to each other
Equal to 90°
Equal to 180°
Equal to 360°

Step-by-step explanation:

When two lines interesect , the angles formed opposite to each other are called vertically opposite angles. Vertically opposite angles [ V.O.A ] are always equal to each other.

Refer to the attachment! In the given figure , p and s are opposite to r and q respectively. Therefore p and r are vertical angles. Similarly , s and q are also vertical angles.

Hence , Our final answer : Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are equal to each other .

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
