Question
If A and B are supplementary, and A = (2x - 6)°, and B = (x + 12)°, find x.Question 51Select one:a.58b.62c.27d.3
Solution
First, we need to understand that if angles A and B are supplementary, then their measures add up to 180 degrees.
So, we can set up the equation:
(2x - 6) + (x + 12) = 180
Simplify the equation by combining like terms:
3x + 6 = 180
Then, subtract 6 from both sides of the equation:
3x = 174
Finally, divide both sides by 3 to solve for x:
x = 58
So, the correct answer is a. 58.
