\green{\underline \bold{<klux>GIVEN</klux> :}} \\  \tt:  \implies cot \: \theta =  \frac{3}{5}  \\  \\ \red{\underline \bold{To \: Find :}} \\  \tt:  \implies 6 \: tan \:  \theta - 5 \: cos \:  \theta = ?

• ACCORDING to given QUESTION :

\bold{As \: we \: know \: that} \\  \tt:  \implies cot \: \theta =  \frac{3}{5}  \\  \\ \tt:  \implies  \frac{b}{p}  =  \frac{3}{5}  \\  \\  \tt \circ \: base = 3 \\  \\  \tt \circ \:   perpendicular = 5 \\ \\   \bold{As \: we \: know \: that} \\  \tt:  \implies h =  \sqrt{ {p}^{2}  +  {b}^{2} }  \\  \\\tt:  \implies h = \sqrt{ {5}^{2}  +  {3}^{2} }   \\  \\ \tt:  \implies h = \sqrt{25 + 9}   \\  \\ \tt:  \implies h =  \sqrt{34}  \\    \\  \bold{for \: finding \: value} \\ \tt:  \implies 6 \:tan \:  \theta - 5 \: cos \:  \theta \\  \\ \tt:  \implies 6 \times  \frac{p}{b}  - 5 \times  \frac{b}{h}    \\  \\ \tt:  \implies 6 \times  \frac{5}{3 }  - 5 \times  \frac{3}{ \sqrt{34} }  \\  \\ \tt:  \implies 2 \times 5 -  \frac{15}{ \sqrt{34} }  \\  \\ \tt:  \implies  \frac{10 \sqrt{34}  - 15}{ \sqrt{34} }  \\  \\ \tt:  \implies  \frac{10 \times 5.83 - 15}{5.83}  \\  \\ \tt:  \implies  \frac{58.3 - 15}{5.83}  \\  \\  \green{\tt:  \implies 7.42}
