Answer:
119 degrees
Step-by-step explanation:
Alright! So this is a supplementary angle, aka it equals 180 degrees. Knowing that, you can set up the equation. Both angle measures combined equal 180 degrees.
So set it up as -2+9x+17x=180
Now just use basic algebra. Combine like terms, So you now have 26x-2=180. Add 2 to both sides, and now you have 26x=182. x=7.
Now plug in the 7 to 17x, since that's the angle you need to find. 7 times 17 is 119. That's your answer, hope this helped!
