Answer:
x = 6
Step-by-step explanation:
1st Group like terms: 13x-5=10x-4x+37
2nd Add similar elements: 10x-4x=6x
13x-5=6x+37
3rd Add 5 to both sides: 13x-5+5=6x+37+5
4th Simplify: 7x=42
5th Divide both sides by 7: 7x÷7=42÷7
6th Simplify: x = 6
Answer:
Step-by-step explanation:
Angles with measures and (or pmore precisely, vertical angle to angle 8x-21) are supplementary (add up to 180°).
Converse to same-side interior angles theorem states that If two same-side interior angles are supplementary, then l║p.
So, to prove that lines l and p are parallel, you have to show that angles and are supplementary.
Thus,
