Answer:
A. There is no solution
Step-by-step explanation:
(12x - 6) = 4x - 9
Evaluate.
4x - 2 = 4x - 9
Deduct 4x from both sides of the equation.
-2 = -9
Multiply both sides by (-1).
2 ≠ 9
Since 2 does not equal to 9, this equation does not make sense and thus does not have a solution.
Answer:
Let the number be x.
Given the statement: The ratio of the measure of the three angles is, 4 : 5 : 6.
Then, the angles be 4x , 5x and 6x respectively.
We know that: The sum of all the measures of angles is 180 degree.
then;
Combine like terms;
Divide by 15 both sides we get;
Then, the measure of each angle of triangle:
