Step-by-step explanation:
[tex] \tt{ 70 \degree + 61 \degree + x \degree + 61 \degree = 180 \degree}[/tex] { Sum of angles of a triangle )
⟶ [tex] \tt{192 \degree + x \degree = 180 \degree}[/tex]
⟶ [tex] \tt{ x \degree = 180 \degree - 192 \degree}[/tex]
⟶ [tex] \tt{x \degree = - 12 \degree}[/tex]
[tex] \red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \tt{x = - 12 \degree}}}}}}[/tex]
