How are the ordered pairs for 9 and 4 -9 similar and how are they different are the two points related by a reflection over and axes in the coordinate plane is so indicate which axis is the line of symmetry between the points if they're not related by a reflection over an axis and the coordinate plane explain how you know

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
