hope you get it thankyou

Answer 2

Answer:

1.tan(15°)can be found if we know the value sin 15 degrees and cos 15 degrees...

2.from the above table.we have the value of tan.sin and cos ratio foe 0°,30°,45°,60°and 90°

3.tan(15°)=√3-1/√3+1

4.hence the value of tan (15°)is √3-1/√3+1.

5.Tan(15°)=(1.732-1)/(1.732+1)=0.2679
