Answer:


Step-by-step explanation:
Solving (9): The equation of the table
We start by calculating the slope (m)

Where:





The equation is then calculated using:

So, we have:

Open bracket


Solving (10):

Required
Find x
Divide both sides by 4.8

By the Pythagoras theorem:-
h^2 = x^2 + x^2
(where h = hypotenuse)
h^2 = 2x^2
h = sqrt2 x
