I think 'neither' because A and C do not connect anywhere, while they are NOT parellel.
Hope this helps.
Answer:
The correct option is A
A) 25 degrees
Step-by-step explanation:
As two parallel line l and m are cut by the line t, the angles formed (x-10)° and < 3 are alternate angles, therefore they are equal to each other.
< 3 = (x-10)° ⇒ Equation (i)
We know that any straight line has a sum of angles equal to 180°.
Consider line t, it is divided into 3 angles due to cutting. Those angles are 85°, (2x)° and (x-10)°. The sum of these angles is 180° as stated before.
85° + (2x)° + (x-10)° = 180°
Find the value of x:
85 +2x + x - 10 = 180
3x + 75 = 180
3x = 105
x = 35°
Substitute it in Equation (i) to get the value of <3
< 3 = (35 - x)°
< 3 = (35 - 10)°
< 3 = 25°
A because 2+2=4 which is simple adding equation
Ratio 3:5:9....added = 17......the largest share will then get 9/17 of the total amount. The largest share will get 54.
So 9/17 of the total money is 54...
9/17x = 54
x = 54 / (9/17)
x = 54 * 17/9
x = 102.....so the total amount of money is 102
the smallest share gets : 3/17 * 102 = 18 <===
the middle share gets : 5/17 * 102 = 30
the largest share gets : 9/17 * 102 = 54
C. Vertical angles are congruent
