Answer:
x = 15
Explanation:
Given m||n, the angles indicated with (6x+20) and (8x-10) are alternate angles and their measures are equal.
So, to find the value of x, we can write the following equation:
8x - 10 = 6x + 20
- Transfer like terms to the same side of the equation.
8x - 6x = 20 + 10
2x = 30
- Divide both sides with 2.
x = 15
