Answer:

Given any straight line and a point not on it, there "exists one and only one straight line which passes" through that point and never intersects the first line, no matter how far they are extended. This statement is equivalent to the fifth of Euclid's postulates, which Euclid himself avoided using until proposition 29 in the Elements. For centuries, many mathematicians believed that this statement was not a true postulate, but rather a theorem which could be derived from the first four of Euclid's postulates. (That part of geometry which could be derived using only postulates 1-4 came to be known as absolute geometry.)

Also draw the line straight line them up. To me it would be best if you use a ruler.

224 7/10 into a decimal

Sidana [21]

Change into an improper fraction. 2247/10 then divide. So, 224.7. Or since you know 7/10 is 0.7 just add 224

Use SSS, SAS, ASA, AAS, or Not Enough Information to identify the postulate or theorem that immediately confirms the congruence

kiruha [24]

Answer:

e) SAS

f) Not enough information

Step-by-step explanation:

e) Sas because there is an angle in between two sides and for that angle is opposite angles

f) Not enough information because SSA is not a theorem

Answer:

The correct option is;

B. 50 km/h

Step-by-step explanation:

The information given in the question are;

The distance between the two cities = 140 km

The direction of motion of the first car = From A to B (left)

The direction of motion of the second car = From B to A

The time after which both cars meet = 1 hour

The time duration it takes after both cars meet for the second car to reach A = 35 minutes

The total time taken by the second car from city B to city A = The time it takes to meet the first car + The time it takes after meeting the first car to reach city A

∴ The total time taken by the second car from city B to city A = 1 hour + 35 minutes = 60 minutes + 35 minutes = 95 minutes

95 minutes = 95/60 hours = 1⁷/₁₂ hours = 1.58 $\bar 3$ hours

The speed of the second car = Distance/Time = 140 km/(1.58 $\bar 3$ hours) ≈ 88.42 km/h

Therefore, let the distance from A of the point the first car meet the second car = x

Therefore, we have;

The distance from B of the point both cars meet = (140 - x) km

Given that both cars meet after one hour, we have;

The distance travelled by the second car coming from city B, after one hour = (140 - x) km = Speed of the second car × 1 hour

88.42 km/h × 1 hour = 88.42 km = (140 - x) km

x = 140 - 88.42 ≈ 51.58 km

The distance from A of the point the first car meet the second car = x = 51.58 km

The speed of car A = (The distance from A of the point the first car meet the second car)/(Time it takes both cars to meet)

∴ The speed of the first car = 51.58 km/(1 hour)

The speed of the first car = 51.58 km/h ≈ 50 km/h (Rounding up to the nearest 10th).
