sin 43° = m
=> sin (90-47°) = m
=> cos 47° = m
 \sin 47 =  \sqrt{1 -  {cos}^{2}47 } \\ sin47 =  \sqrt{1 -  {m}^{2} }   \\  \tan47 =  \frac{sin47 }{cos47}  =  \frac{m}{ \sqrt{1 -  {m}^{2} } }

azmeenshabana10: Mistake in last step wrong value of cos and sin has been putted it should be interchanged with each other

Answer:

Tan 47 =\frac{\sqrt{1-m^2}}{m}

Step-by-step explanation:

Given :sin 43° = m

To Find : Tan 47

Solution :

sin 43° = m

sin (90-47) = m

sin(90-\theta)=cos \theta

Cos 47 = m

We know that Sin^2\theta =1- Cos^2\theta

Sin^2 47 =1- Cos^2 47

Sin 47 =\sqrt{1- m^2}

Tan 47 = \frac{sin 47}{Cos 47}=\frac{\sqrt{1-m^2}}{m}

Hence Tan 47 =\frac{\sqrt{1-m^2}}{m}
