Answer: x = 15
Step-by-step explanation:
Hi!
These are supplementary angles, which means they both add up to 180°
Therefore,
9x+10 + 1x + 20 = 180
to solve, combine like terms
10x + 30 = 180
Then subtract 30 from both sides
10x = 150
now divide 10 from both sides leaving x by itself
x = 15
Hope this helps and have a nice day!
