Answer:
x=6
Explanation:
these parallel lines are cut by a transversal line, forming different angles.
10x is a corresponding angle to 6+9x, so we can set them equal to each other,
10x = 6 + 9x
- 9x -9x (we want to isolate the variable(x), so we group the x's)
[1] x = 6
so, we know that x = 6
(if you want to check:
10x = 6 + 9x
60 = 6 + 54 is a true statement, confirming that x=6)
