$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Since it's a right angled Triangle we can } \\ \textbf{ use Pythagoras theorem }$

$\sf{Cos (29°) = \dfrac{b}{c}}$

$\sf{Cos (29°) = \dfrac{b}{260}}$

$\sf{b= 260\cdot Cos (29°) }$

$\sf{b= 260\cdot 0.875 }$

[ $\textsf{Cos(29°)= 0.875}$ ]

$\sf{b= 227.5 in }$

$\textsf{I hope you understood the procedure}$
