I need help with this question ASAP. Please help somebody thank you. It will be greatly appreciated. It is for my maths homework.
As the question instructs you to use the property 'when x is small, tanx = x', I assume tan ruling is not what you are meant to do.
Method:
Let the angle subtended be x
tanx = 30/4000
= 3/400
as tanx = x, and tanx = 3/400
thus x= 3/400 radians (using the property
convert 3/400 radians to degrees to the nearest minute (x180/pi) for the final answer
