Answer:
n = 13
Step-by-step explanation:
1. (9n-8) and (6n-7) combined equal 180 degrees, and we can translate that into an equation and then solve it: [tex]9n - 8 + 6n- 7 = 180[/tex]
2. (Solving)
Step 1: Simplify both sides of the equation.
- [tex](9n+6n)+(-8-7) = 180[/tex]
- [tex]15n-15=180[/tex]
Step 2: Add 15 to both sides.
- [tex]15n-15+15 = 180+15[/tex]
- [tex]15n = 195[/tex]
Step 3: Divide both sides by 15.
- [tex]\frac{15n}{15} = \frac{195}{15}[/tex]
- [tex]n = 13[/tex]
Therefore, n = 13.
