Answer:
x =20
Step-by-step explanation:
In triangle AOB
OA and AB are equal so the angles opposite to this sides are equal
O = 3x+10
BD is bisect by AC
opposite angles are equal
so angle BOA = angle COD
In triangle COD
sum of triangle is 180
so
180=2x+3x+10+3x+10
180 =8x + 20
180 - 20 =8x
160 =8x
160/8 = x
20 = x
x =20
