~Set up an equation and solve for x :
[tex] \large{ \tt2x \degree - 21 \degree = 87 \degree}[/tex] [ Being alternate angles ]
Since we want to get rid of constant on left hand side , add 21 on both sides :
⟿ [tex] \large{ \tt{2x - 21 \degree + 21 \degree = 87 \degree + 21 \degree}}[/tex]
⟿ [tex] \large{ \tt{2x \degree = 108 \degree}}[/tex]
Divide both sides by 2
⟿ [tex] \large{ \tt{ \frac{2x}{2} = \frac{108}{2} \degree}}[/tex]
⟿ [tex] \large{ \tt{x = 54 \degree}}[/tex]
☥ [tex] \boxed{ \boxed{ \large{ \text{Our \: Final \: Answer : } \underline{ \tt{x = 54\degree}}}}}[/tex]
