Question

i need help quicklyyyyyy

Answer 1

Here is your answer

In given circle
BN is diameter
and, OC and OM are radius
we know that diameter= (1/2) radius

So,. 1) BN= (1/2) OC
OC= 2BN


2). Since OC and OM both are radius of same circle
so, OC=OM
NOW, OC + OM = BN since OC and OM both are radius and BN is diameter of the same circle
so, 2r = d

3). Now, according to figure Angle CON = 90°
By linear pair Angle BOC= 90°

So, CON=BOC
