Answer:
85+(5x-10)=11x+3 (sum of two non-adjacent interior angle is equal to exterior angle )
75+5x=11x+3
75-3=11x-5x
6x=72
x=72/6
x=12
You can look on the app Socratic to help you.
Hi!
Put in the values for x and y.
(3 · 3 - 12)-(12 · 3 · 6 - 10)
Solve
(9 - 12)-(216 - 10)
-3 - 206
-209
The answer is -209
Hope this helps! :)
I may be wrong but I believe that <1=<2
