Answer:
Look below.
Step-by-step explanation:
One property of a cyclic quadrilateral is that the opposite angles are supplementary. Angles ABC and ADC are opposite; therefore, supplementary. We know that angle x is supplementary to angle ABC because they are on the same line. We know that angle y is supplementary to angle ADC because they are on the same line.
ABC + ADC= 180 degrees
ABC + x= 180 degrees
ABC + ADC = ABC + x
- ABC -ABC
ADC= x
ADC+ y= 180 degrees
ADC + ABC= 180 degrees
ADC+y= ADC+ABC
-ADC -ADC
y=ABC
ABC=x ADC=y
ABC + ADC= 180
Property of substitution:
x+y=180
Answer:
40 :)
Step-by-step explanation:
2y^3+4y^3 is 6y^3
-7y^2+10y^2 is 3y^2 ***NOTE: 10y^2 is from the 6y^2+4y^2
-7y+3y is -4y
Answer: 6y^3+3y^2-3y

10. p ![\leq 17](https://tex.z-dn.net/?f=%5Cleq%2017)
11. I forgot how to do this one.
And sorry I don't have the time to graph it at the moment but I hope this helps at least a little
