Answer:
37 degrees
Step-by-step explanation:
As XW and YZ are parallel lines, you can use the co-interior angle rule to solve for x.
This is when you see a C-shape between parallel lines. The rule states that the sum of these two co-interior angles is 180 degrees.
Therefore,
⇒ 
⇒
[collect like terms of x]
⇒
[add 5 to both sides]
⇒
[divide both sides by 5]
Hope this helps! :D
6×10^4
We use 6 because the # has to be greater than or equal to 1 but less than or equal to 10.
10^4=10000
10000×6=60000
