"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 "
