x=61
Step-by-step explanation:
The angle above is a supplementary angle.
What is a supplememtary angle?
- angles that when added up, will result to 180°
Back to the question.
(2x+3)+(x-6)=180
First, collect like terms:
2x+3+x-6=180
Move the constant to the right:
3x-3=180
3x=180+3
3x=183
Divide both sides:
x = 61
