The sum of all exterior angles add up to 360º. To find the missing 3rd exterior angle subtract the sum of the first two exterior angles from the total sum of all exterior angles.
360º - 220º = 140º
The measure of the third exterior angle is 140º.
A´(-2,-4) B´(-3,-7) C´(-1,-8) D´(1,-6)
Answer:
7 maybe this is the answer please correct me if I'm wrong
Answer:
The correct conversion is B)
B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s
Hence,
200 km/h ⇒ ![\dfrac{200 \times 1000}{60\times 60}=55.56\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7B200%20%5Ctimes%201000%7D%7B60%5Ctimes%2060%7D%3D55.56%5C%20m%2Fs)
Step-by-step explanation:
Given:
An airplane is traveling at a speed of 200 km/h.
The correct conversion is B)
B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s
Reason:
For Converting Speed unit km/h ⇒ m/s
First we need to convert km ⇒ meter
So 1 km = 1000 meter
Secondly, in hour ⇒ seconds first we need to convert it into minutes then to seconds
hour ⇒ minute ⇒ seconds
So 1 hour = 60 minute and 1 minute = 60 seconds
Therefore, 1 hour = 60 min × 60 sec
Hence,
200 km/h ⇒ ![\dfrac{200 \times 1000}{60\times 60}=55.56\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7B200%20%5Ctimes%201000%7D%7B60%5Ctimes%2060%7D%3D55.56%5C%20m%2Fs)
