Answer:
Cody and Lara are 12 meters apart.
Step-by-step explanation:
You need to use the Pythagorean theorem.
Draw a triangle with the hypotenuse as the distance between Brenda and Lara, the leg should be the distance between Brenda and Cody and the base should be the distance between Cody and Lara.
Then you plug in the distances for each side of the triangle.
The distance between Brenda and Lara or the hypotenuse of the triangle is 20m. We also know that the distance between Brenda and Cody or the leg of the triangle is 16m.
Then, set up an equation using the pythagorean theorem.
A^2+B^2=C^2
In our case we know A which equals 16 and we know C which equals 20.
Now, you square 20 or the hypotenuse and then subtract 16 squared.
20^2 = 400
16^2 = 256
400 - 256 = 144
144 = 12^2
12 meters is the base and the distance between Cody and Lara.
