Alona [7]

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: 9n - 8 + 6n- 7 = 180

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (9n+6n)+(-8-7) = 180
  • 15n-15=180

Step 2: Add 15 to both sides.

  • 15n-15+15 = 180+15
  • 15n = 195

Step 3: Divide both sides by 15.

  • \frac{15n}{15}  = \frac{195}{15}
  • n = 13

Therefore, n = 13.
