Answer 2

Answer: $\frac{8}{3}$

Step-by-step explanation:

• Given, cos θ=$\frac{3}{5}$ so, base=3 and hypotenuse=5.
• Perpendicular=$\sqrt{5^{2}-3^{2} }$

                                =$\sqrt{16}$

                                = 4

• So, Sin θ=$\frac{4}{5}$ and tan θ=$\frac{4}{3}$
• Now, 5 Sin θ - tan θ

               ⇒ $5*\frac{4}{5}-\frac{4}{3}$

               ⇒$\frac{12-4}{3}$

               ⇒ $\frac{8}{3}$

• Hence, the value of the given expression is  $\frac{8}{3}$.
