hey sweetsh angell
it is a wierd question
but i have tried to solve it
is the answer 160 degree
i am not sure
plz chk it and do inform me..
if not
tell me the answer
i'll try n figure out
thanks :)
its 160
says so in markscheme
Thanks for da pic attached for the answer bt if u can xaplain y u took those angles =/
i drew a common strait line for the points 'n found out that they were 5 dergrees lesser so 85-5=80 and 80+80=160 can we tke it dat way or can u plz xplain how u got it
plus the question says calculate not find out so can we still use the diagram?? ???

look at the image
let the intersection point be called X
PQX is a straight line
<RQX = 180 - <PQN - <NQR = 10 degree
same for the other side
therefore <XRQ = <RQX = 10 degree

angle sum property of triangles = add up to 180
therefore <QXR (the question) = 180 - 10 -10 =160
hope it helped

Just what the words suggest.

A slipring is a conductive ring - usually solid - on which a conductive brush/contact rides so as to complete a circuit even as the ring turns.
chk out this website
great website
