In Figure,/_A=60^(@) and /_ABC=80^(@), find /_DPC and /_BQC

In the given figure, /_ AOB = 90^(@) and /_ ABC = 30^(@) . Then /_ CAO = ?

O is the centre of a circle and AC is one of its diamter. If /_AOB = 80^@ and /_ACE =10^@ , then find the value of /_BEC .

If in any Delta ABC,A=30^(@) and B=60^(@), then find a:b:c

If m(arc APC)=60^@ and /_BAC=80^@ . Find /_ABC

O is the centre of a circle.AC and BD are two chords of the circle intersecting each other at P.If /_AOB=15^(@) and /_APB=30^(@), then 3(tan^(2)/_APB+cot^(2)/_COD) is equal to

In the given figure, angle A = 60^(@) and angle ABC =80^(@) , then find angle BPC .
