"hello students welcome to lido q a video
session i am sef your maths tutor and
question for today is
in figure 10.36 a b and c are three
points on a circle with center
o such that angle boc
is equal to 30 degree angle aob
is equal to 60 degree if d is the point
on the circle other than the r abc
find angle adc to find this angle d
adc let us see what is given so from the
question it is given that
angle aoc is equal to
angle aob plus angle boc
so angle aoc is equal to 60 plus 30.
hence angle aoc is equal to 90 degree
now it is known that an angle which is
subtended by an arc at the center of the
circle
is double the angle subtended by an arc
at any part
point on the remaining part of the
circle so you can see
this is angle subtended
by an arc at the center
and this angle center of the circle is
double the angle subtended by an arc at
any point on the remaining part
of the circle hence we can relate it
like this i'll write the statement
and angle
subtending
by are
at center
of the circle
is double the angle subtended by
subtended by any point on remaining
part of the circle
so from this we can say that
angle adc equal to half of
angle aoc
and this is half of 90
which is equal to 45 degree
hence angle
adc
is 45 degree which is required measure
if you have any query regarding this you
can drop it in our comment section
and subscribe to lido for more such q a
thank you for watching
