So First move terms 8=3a-4
Next you calculate -3a=-4-8 then
Next you will Divide both sides by -3
-3a=-12 then your answer would get a=4
All you have to do is take your x value (m) and look for key words (more than) whicg tells you to add so, m+119
Answer:
Corresponding angle theorem, vertical angle theorem, and the transitive property of congruence.
Step-by-step explanation:
Considering a set of parallel lines cut by a transversal. (Refer the attached image).
Now that lines J and K are parallel, then by "corresponding angle theorem"
![\angle 1=\angle 5](https://tex.z-dn.net/?f=%5Cangle%201%3D%5Cangle%205)
By "vertical angle theorem"
![\angle 5 = \angle 7](https://tex.z-dn.net/?f=%5Cangle%205%20%3D%20%5Cangle%207)
Using, "transitive property of congruence"
![\angle 1 = \angle 7](https://tex.z-dn.net/?f=%5Cangle%201%20%3D%20%5Cangle%207)
And that is our required proof. In this whole proof we have used "corresponding angle theorem", "vertical angle theorem", and the "transitive property of congruence".
