Answer:

k = 13

Step-by-step explanation:

1. A straight angle is equal to 180 degrees, and a right angle is 90 degrees. With this information and the angles of (4k-7) and (3k+6), we can build an equation of:

  • 4k-7+90+3k+6=180

2. (Solving)

Step 1: Combine like terms.

  • 4k - 7 + 90 + 3k + 6 = 180
  • (4k+3k) + (-7+90+6) = 180
  • 7k + 89 = 180

Step 2: Subtract 89 from both sides.

  • 7k + 89 - 89 = 180 - 89
  • 7k = 91

Step 3: Divide both sides by 7.

  • \frac{7k}{7} = \frac{91}{7}
  • k = 13
