Parallel lines have the same slope.
I Domitila get hungry :
Step-by-step explanation:
A number x divided by -1 is at least -4.
x / -1 ≥ -4
Multiply both sides by -1.
x ≤ 4
Remember, when multiplying or dividing by a negative, you must change the sign's direction.
~Hope I helped!~
I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
Answer:
That is correct
Step-by-step explanation:
180° rotation about origin just means that you have to flip the pre-existing image across the x-axis
Good job!
