Answer:
Y = 40
Step-by-step explanation:
I do not understand that language but if it is asking what Y is equal to when x is equal to 30 degrees and EFG is a straight line.
1. 3Y + 2X = 180 (Straight angle)
2. X = 30 (given)
3. therefore 2X = 2x30
= 60
4. Therefore 3Y + 60 = 180
5. 3Y = 180 - 60
6. 3Y = 120
7. Y = 120/3
8. Y = 40
