We would need to figure out the gradient of each "pair", as provided in the image.
The equation of the gradient is found by,
m =

Parallel lines mean they have the same gradient
Perpendicular lines will follow the formula

"None" will apply to those that do not follow either.
Now we calculate the gradient of the pairs given to us by substituting the x and y values.
RS =

=

TU =

=

Therefore, the "pair" RS and TU will be NONE.
ST =

= -1
RU =

=

Therefore, the "pair" ST and RU is also NONE.
Hope this helped! Feel free to ask me if there's any part of the working you don't understand :)
The answer is [($109.90-$98.91)/$109.90]X100%
Answer:
aka 9 units
Step-by-step explanation:
Its pretty simple so what u do is count the sqaures then multiply them and ill do it for you
H=3
B=6
and the formula for a triangle is A=
so its 3x6/2=9
The answer is 9
