In ΔPQR, what is the m∠Q?.
2 answers:
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
