Answer:
Yes
Step-by-step explanation:
For a triangle to be rights angled.
It should follow Pythagoras theorem.
Pythagoras theorem states that if sides containing right angle is a and b
then is given by
hypotenuse = 
As hypotenuse is always the greatest side
Out of the given sides 144m,165m,219m
219 can only be hypotenuse
Thus side containing right angle will be 144m and 165m .
Lets plug these value in formula of Pythagoras theorem
As we can see that hypotenuse calculated by us is same as given in problem.
Thus the given triangle is right angled.

Part (9)</u></h3>
The values of x for which g(x) < f(x) are the values of x between the points of intersection of the two functions: points D and A.
From part (2) of the question, we found that A = (3, 0).
From part (5) of the question, we found that D = (-4, 7).
Therefore, the values of x for which g(x) < f(x) are -4 < x < 3.
In interval notation this is: (-4, 3).

Answer:
(3, 6); (-3, 18)
Step-by-step explanation:
We equate the 2 expressions in x :-
x^2 - 2x + 3 = -2x + 12
x^2 - 2x + 2x + 3 - 12 = 0
x^2 - 9 = 0
(x - 3)(x + 3) = 0
So x = 3 or -3.
When x = 3, f(x) = -2(3) + 12 = 6.
When x = -3, f(x) = -2(-3) + 12 = 18.
