Answer:
C=78
D=102
Step-by-step explanation:
co-interior angles are sepplementary
When reflecting about the y axis, you x coordinate changes sign, so your answer would be D) (-2;-4)
The second answer is D) (the bottom right one)
The answer would be 6. This be because 6 + -8 = -2.
17/56
So to make sure that you are subtracting right, you make the denominators the same. So the denominator is 56 because it is a common number for 7 and eight. And then whatever you do to the bottom you got to do to top so time seven by eight and 4 which is 49 and 24 so 49-24 is 17/56 so the answer would be this because you can’t simplify the answer down.
= 204800. 204800 / 
= 800.
