x = 20°
Step-by-step explanation:
The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.
3x + 2x simplifies to 5x. 5x must equal 100.
100/5 = 20.
Therefore x = 20.
Answer:
3.1
Step-by-step explanation:
19.9 = 9y - 8
+8 +8
27.9= 9y
/9 /9
3.1 = y
Check:
9(3.1) - 8 =
27.9 - 8 = 19.9
I think it would be 12(2-3)
Hope this helps!
