The sum of the 3 inside angles of a triangle needs to equal 180:

11x-5 + 6x + 5 + c = 180

Combine like terms:

18x = 180

Divide both sides by 18:

X = 10

Solve for Q:

11x -5= 11(10) -5 = 110-5 = 105 degrees

Answer:

105°

Step-by-step explanation:

Total angle = 180

x + (11x - 5) + (6x + 5) = 180

18x = 180

x = 10

m∠Q = 11(10) - 5 = 105
