@ParthKohli i think this is just like last time

parthkohli · Answer

$\Large \color{MidnightBlue}{\Rightarrow {180(7) - 360  \over 7}}$

$\Large \color{MidnightBlue}{\Rightarrow {1260 - 360 \over 7} }$

$\Large \color{MidnightBlue}{\Rightarrow {900\over 7} }$

$\Large \color{MidnightBlue}{\Rightarrow 128.6 }$
