Step-by-step explanation:

taking the rule of angles which state that angles on a straight line add up to 180°

then we take the solution adding the expression then equate to 180°

;5x+4+x-2+3x+7=180

like terms together

5x+x+3x+4+-2+7=180

=9x+9=180

9x=180-9

9x=171

getting the value of x we divide by nine both sides

x=171/9

x=19°
