The answer would be D because triangles add up to 180 degrees and the two angles together only add up to 140, so the missing angles would be 40 degrees

D. 40 degrees

This is the answer because 70+70=140
There is 180 degrees in a Triangle. So you must subtract 140 from 180. 
180-140=40.

Elena runs for 28 seconds and finishes at 250 seconds what is her velocity please explain
ExtremeBDS [4]

Answer:

The velocity is 8.93 meters/second.

Step-by-step explanation:

It is given that  Elena runs for 28 seconds and finishes at 250 meters.

Here the displacement is 250 meters and the time is 28 seconds.

We know that  V=\dfrac{\text{Displacement}}{\text{Time}}

Substitute displacement = 250 and time = 28 in above formula.

V=\dfrac{250}{28}

V\approx 8.93 meters/second

Hence, the velocity is 8.93 meters/second.
