3 0

Answer:

Explanation:

In shapes with 4 angles, the angles must all add up to 360. So in this case we have 2 90 degree angles which added together equals 180, and an angle that is 140. If you add that together, you get 320. That is 40 less than 360. So that means that D is 40 degrees. Now looking at angle H, it looks the same as D, so I would say that H is also 40 degrees.

Hope this helps!

The times for five sprinters in a 50 meter dash were 6.72 seconds 6.4 seconds 6.08 and 7.03 seconds in 6.75 seconds right these

andreev551 [17]

Answer:

Fastest to slowest = 6.08 > 6.4 > 6.72 > 6.75 > 7.03

Step-by-step explanation:

The person who completes the 50-meter race within the shortest possible time is the fastest sprinter. Here, the third sprinter crossed the line in 6.08 seconds, whereas the 4th sprinter crossed the line in 7.03 seconds. That is why the third sprinter has won the race, and he becomes the fastest. On the contrary, the fourth person takes the most time to complete the race, meaning he is the slowest.
