Answer:Each pair of interior angle and the exterior angle
So the exterior angle = 360° - the interior angle.
Answer:
Step-by-step explanation:
- 3x-2y =7
- x+2y= -3
- 4x=4
- x=4/4
- x=1
- 3x-2y=7
- 3(1)-2y=7
- 3-2y=7
- -2y=7-3
- -2y=4
- 2y=-4
- y=-4/2
- y= -2
- Verify solution
- x+2y= -3
- 1+2y= -3
- 2y=-3-1
- 2y= -4
- y= -4/2
- y= -2
Answer:
(a)
(b)
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis
Step-by-step explanation:
We have given points are
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by
So
(b) Equation of line is given
This line is parallel to x axis so slope will be zero
So equation of line will be
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis
