71 degrees

anonymous · Answer

assuming the diameter is perpendicular to the base

aonz · Answer

yea i found x i just need to find y

anonymous · Answer

there is probably some theorem on angles and circles you should know, notice that the upper side of that parallelogram is the radius of the circle.

anonymous · Answer

shouldn't x and y be same??

aonz · Answer

def not they are not parallel

anonymous · Answer

the angle opposite to 121 and below y is 109..so that 121+71+59+109=360...so y=180-109=71..correct me if m wrong

aonz · Answer

but it isnt supplementary so one below y isnt 109

anonymous · Answer

what isn't supplementary?360 condition??yes it is

aonz · Answer

points are NOT concyclic...

anonymous · Answer

i don't think so...well..wait for a better solution

anonymous · Answer

the answer i think lies in this theorem that...
the angle subtended by a part of the circle at the centre is double the angle subtended by the that same part of the circle in the remaining part of the circumference...
which gives y very easily...

aonz · Answer

hmm well i am thinking about that :/
