Answer:
A. 6
Step-by-step explanation:
The angles are in the ratio of 5:6:9.
Let the angles be represented by:
5x, 6x, and 9x.
The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9
The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.

Answer:
Step-by-step explanation:
x^2 - 22x = 10
Next step is to complete the square on the left hand side of the equation and it would be balanced by adding the same number to the right side of the equation. It becomes
x^2 - 22x + (22/2)^2 = 10 + (22/2)^2
x^2 - 22x + (11)^2 = 10 + (11)^2
x^2 - 22x + (11)^2 = 10 + 121
x^2 - 22x + (11)^2 = 131
x^2 - 22x + 121^2 = 131
(x - 11)^2 = 131
Taking square root of both the left hand side and the right hand side of the equation, it becomes
x - 11 = ±√131
x - 11 = ±11.45
Adding 11 to the left hand side and the right hand side of the equation, it becomes
x - 11 + 11 = ±11.45 + 11
x = 11.45 + 11 or x = -11.45 + 11
x = 22.45 or x = - 0.45
Y = 2x + 3
y = 2(3) + 3
y = 6 + 3
y = 9
