Question

pls give detailed solution so that i can understand it

Answer 1

Minimum error will be there when the product of tan x and π will be minimum .
Take the value of π =3.14.
Now product of tan x and π should be minimum . For that , check the value of tan x to minimise this product.
We know that tan 0° = 0 which will give results = 0 . It means 0 errors. That's why value of the angle will be 0°
I hope it helped.
