Question

Would mean a lot if you could help me out don’t answer it if you don’t know the answer

Answer 1

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!
