Answer:
Please check attachments
Step-by-step explanation:
Here, we went to sketch points
We can have them through the array, please check
For the 180 degrees counterclockwise rotation, we have that
(x,y) will become (-x,-y)
So E’ is (4,-5)
Kindly note that the first attachment is E while the second is E’
Answer:
in my opinion i think its c
but somebody else might think different
Answer: y=28 degrees
Step-by-step explanation:
- To find angle B, all we have to do is subtract 145 from 180 since they're supplementary angles- so angle B is 35 degrees
- Now we can find x, by subtracting 14 from 35-> x=21
- We can create an equation using what we know about B to find y: 35= 63-y
- Solve the equation to get y=28 degrees
In this problem we used supplementary angles and algebra. We also used congruency.
