X+22+2x-13=180 degrees
3x + 9 =180
3x=171

\large\underline{ \boxed{ \sf{✰\:Notes }}}

✟ Now let ✟

  • ➣Let these two parallel line be p and q
  • ➣ and angle "x + 22" be a
  • ➣ and angle "2x-13" be b


\rule{70mm}{2.9pt}


\underline{ \boxed{ \sf{✰ \:Concept \: used }}}

  • ➣ Here given two lines are parallel and also know as transversel
  • ➣ angle a and b are same side interior angle
  • ➣ and given two angle are supplementary
  • ➣ and sum of supplementary angle is of 180⁰
  • ➣ soo the equation formed is a+b =180⁰

★ Now let's solve according to concept


\qquad\rm{➛ \: x+ 22+2x-13 = 180 \degree}\\\qquad \rm{✮solving \: like \: terms✮} \\ \qquad\rm{➛ \: 3x + 9 = 180 \degree} \\ \qquad\rm{➛ \: 3x = 180 - 9} \\ \qquad\rm{➛ 3x = \: 171} \\ \qquad\rm{➛x = (171)/(3) } \\ \qquad\rm{➛ \: x = \frac{ \cancel{171}}{ \cancel3} } \\ \qquad\rm{➛ \: x = 57 \degree}

★ More info ★

  • Supplementary angle :- An angle that, when added to another referenced angle, produces an angle of 180 degrees.
  • ➣Transversal :-A line which traverses or intersects any system of other lines transversely.
  • Interior angles :- The inner angle between two sides
