.
In the given figure, rays OA, OB, OC and OD are such that
ZAOB
56°, ZBOC=100°, /COD = x° and ZDOA = 74°.
Find the value of x.
Hint. Sum of all the angles around a point is 360°.
solution
sum of all angle is 360 degree (given<aob=56
let the<cod be x°
ATQ
100+56+74+X=360(sum of all angle)
100+130+X=360
230+X=360
X= 360-230
X=130°(<COD)
