Answer 2

Solution:-

• See both angles are constructing supplementary angles
• Hence their sum will be 180°

$\qquad{:}\longrightarrow$$\sf \angle {ABD}+\angle {CBD}=180°$

$\qquad{:}\longrightarrow$$\sf 2x+x+40=180$

• Simplify

$\qquad{:}\longrightarrow$$\sf 3x+40=180$

• Interchange sides and get x

$\qquad{:}\longrightarrow$$\sf 3x=180-40$

$\qquad{:}\longrightarrow$$\sf 3x=140$

$\qquad{:}\longrightarrow$$\sf x={\dfrac {140}{3}}$

$\qquad{:}\longrightarrow$$\sf x=26.3$

$\therefore\sf m\angle {C}=26°_{(Approx)}$

Hence Correct option is none of the Above
