Answer:
It will take <u>600 seconds</u> for Mia to run 400 meters.
Step-by-step explanation:
Given:
Mia ran 2/3 meters per second.
Now, to find how long will it take for Mia to run 400 meters.
Distance = 400 meters.
Speed = 2/3 meters per second.
So, to find the time it will take for Mia we put formula:






Therefore, it will take 600 seconds for Mia to run 400 meters.

Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

And we can find a easily using pythagorean theorem:

Solving for a:


Therefore:
