Answer:
Step-by-step explanation:
If lines OA and OC trisect angle NOD, then
By angle addition postulate:
If line OB bisects ange NOD, then
Angle AOB is 20 degrees less than angle NOA, then
By angle addition postulate,
Thus,
and
9.50 Times x equals 247 or 9.50 times x is greater than or equal to 247
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
