Mrs. Bullock is teaching a 5th grade class. She is standing 6 meters in front of Tessa. Anna is sitting to Tessa’s right. If

Anna and Mrs. Bullock are 10 meters apart, how far apart are Tessa and Anna?​

Answer:

8 meters

Step-by-step explanation:

Imagine a triangle with the three points: Mrs. Bullock, Tessa and Anna. They form a right triangle, so you can apply the pythagorean theorem.

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.

6^2 + b^2 = 10^2

36 + b^2 = 100

b^2 = 64

b = 8
