Question
If A and B are vertical angles, and A = (12x + 6)°, and B = (20x -10)°, find x.Question 28Select one:a.4b.2c.- 2d.30
Solution
Since A and B are vertical angles, they are equal. Therefore, we can set the two expressions equal to each other and solve for x.
12x + 6 = 20x - 10
First, we can subtract 12x from both sides to get:
6 = 8x - 10
Then, add 10 to both sides to isolate the term with x:
16 = 8x
Finally, divide both sides by 8 to solve for x:
x = 2
So, the correct answer is b. 2.
