Answer:
AU(B n C)= (1,3,5,7,9,6)
Step-by-step explanation:
BnC= (6)
AU(Bn C)= (1,3,5,7,9)U(6)
A U(B n C)= (1,3,5,7,9,6)
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
