We let x and y represent the two angles,
y = 2x + 6
It was stated in the problem that these angles given are a linear pair. Angles in linear pair are said to add up to 180 degrees. Thus,
y + x = 180
2x + 6 + x = 180
3x = 174
x = 58°
y = 122°
In this quetion we have to find the coordinate of point C on rotation by 180 degree about origin .
The rule for rotation by 180 degree about the origin is
It means , the x and y coordinates become opposite. That is
The new coordinate of point C (-3,4) is
And that's the required answer.
Number of thousands on the amount of the loan is

Answer:
Step-by-step explanation:
Given that,
The area of a square is given by :
A = s² ....(1)
Where
s is the side of the square.
Differentiating (1) wrt s.
Put s = 10 in the above equation.
So, the rate of change of the area of a square is 20 units
