Hi, a number line that goes up and down is called the y-axis. However, a number line that goes left and right is called the x-axis.
The sum of a straight angle is 180°
So 77+x=180
Subtract 77 from both sides and the equation is
x=77
The measure of the other angle is 77°
We start with
We can factor x at the numerator:
So, assuming (otherwise the expression would make no sense) we can simplify it:
This equation has no roots, so we can't simplify it any further.
