Answer:
20°
Step-by-step explanation:
since AB=AO. (given)
=>angle AOB= angleABO = 3x+10.....(1)
since OC= CD. (given)
=> angleCDO = angle COD= 3x+10....(2)
[ from eqn (1) since AOB= COD]
in triangle COD
=> < C+< O + < D= 180
=> 2x+(3x+10)+(3x+10)= 180......from (2)
=> 8x+20= 180
=> 8x= 160
=> x= 20° answer
