$\huge \color{purple} \mathcal{ \colorbox{pink}{\colorbox{white}{Solution ❥}}}$

These 3 angles form linear pair.

$\large{\sf{90~+~30~+~2x~=~180}}$

$\large{\sf{120~+~2x~=~180}}$

$\large{\sf{2x~=~180~-~120}}$

$\large{\sf{2x~=~60}}$

${\sf\bold{x~=~30°}}$

$\purple{\sf\bold{Option~2.}}$

Answer 2

30°answer

30°+90°+2x=180°

120°+2x=180°

2x=180°-120°

2x=60°

x=60°

2

option (b) x= 30°
