Q3bi
i know its length= thita * radius
but why do we add SIN to the thita  ???

Meticulous:
halosh..please post the q paper. or its link. for the 17000 time i do edexcel..lol

actually if u notice that a right angle triangle can be formed from the those two lines
the radius is 3\2 which is equal to 1.5
this will be the hyp of a right angle triangle
so the angle 6.5 can be used to find the opp of the triangle which will be the extension
so sin6.5*1.5 will be the extension(opp)
