The coordinates of the vertices of LMN acquired a -ve sign to form the image L'M'N'. The line passes through the origin.
Step-by-step explanation:
When a point is rotated through 180° about the origin clockwise/anticlockwise, the coordinates of the object point T (h,k) takes a new position (-h,-k) to form the image T'. A line joining an object point to its image point will pass through the origin that is the center of rotation.

Answer:X= 10.1
Angle answer is correct
Step-by-step explanation: 7X+1+108.3=180
7X+109.3=180
-109.3
7X= 70.7
Divide by 7
X = 10.1

Answer:
the smaller angle is 35 degrees.
Step-by-step explanation:
complementary angles are 90 degrees, so you would set your entire equation to 90.
we can use the variable x to represent the unknown smaller angle. we know that the larger angle is 20 more degrees than the unknown smaller angle (x). we can set up the equation like this:
x + x + 20 = 90
the first x represents the smaller angle and the x + 20 represents the other angle, which is 20 more than the smaller angle. we set it to 90 because we know that the entire angle will be 90 degrees
move variables and constants to opposite sides of the equal sign and combine like terms:
x + x = 90 - 20
2x = 70
divide both sides by 2 to isolate 90:
x = 35
you can plug x back into the equation to check your answer if you want
hope this helps!! :)
