Answer:
Angle ECA=68°
Explanation:
To solve, set the two angles equal to each other.
14x-2=12x+8
Now, we need to make the x's go to one side of the equation. This is because we need the x's to equal something. Otherwise, we can't solve. To do this, I am going to move 12x to the right. Remember, if a number is positive on one side, it will be negative when you move it to the other.
2x-2=8
Now, we need to add two to both sides.
2x=10
Now divide both sides by 2.
x=5
Now to solve, plug in 5 for x.
14(5)-2= ?
70-2=68
Angle ECA=68°
