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°
Answer:8000 i think
Step-by-step explanation:
=20 to the power of nine-20 to the power of four=20 to the power of three.
20 to the power of three is 8000.
Hope this helps.
distance= rate ÷ time
time= rate ÷ distance
time= 200 km/hr ÷ 1400 km
time= 1/7 hr or 0.1428... hr
The net force will be 3 N to the right.
12N - 8N = 4N - 7N= -3N. 3N is the net force to the right.
