Answer:
<h2>4 and 8</h2>
Step-by-step explanation:
4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.
4 and 3 are supplementary angles (they both add up to 180°).
4 and 1 are vertically opposite angles and are equal to each other.
<u>From the above explanations, only 4 and 8 are corresponding angles. </u>

16 - x = 4
16 - 12 = 4
x = 12
Make it a trinomial by using the FOIL method.

It doesn’t really matter which variable you isolate first but usually you would use the one that’s by itself already. like for example one of the equations was y = 8. you would already have your y solve for so you would just have to plug that in for y in the other equation. personally, i usually do x first unless one of the equations has either x or y by itself already. i think its easier to just do x first and then solve for y after that, but it just depends on what the equations are; sometimes it might be easier to just do y first. hope this helps!
