y=4
Step-by-step explanation:
4y+3=19
=4y=19-3
=y=16/4=4
Answer:
150 degrees
Step-by-step explanation:
- Let the supplement = x
- So the angle you want is 5x
- Then [x + 5x] = 180 because they are supplementary.
- Solving. 6x = 180. Then x = 30.
- So the angle is 5x = 5×30 = 150 degrees
X=15 is your answer. Give brainliest if possible.
