The equation that solve for x is as follows;
70 + 60 + x = 180
<h3 /><h3>How to find an angle?</h3>
The equation that can be used to find the measure of angle x can be found as follows:
60 + 70 + y = 180
Therefore,
130 + y = 180
subtract 130 from both sides
130 - 130 + y = 180 - 130
y = 50°
70 + 60 + x = 180
130 + x = 180
x = 180 - 130
x = 50° 
x and y are  vertically opposite angles.
