Answer 1

Melissa and her younger sister are 5 meters apart.

Step-by-step explanation:

They form a right triangle,

• Height = her older brother 12 meters directly ahead of her .
• Base = her younger sister directly to her right.
• Hypotenuse = Melissa's brother and sister are 13 meters apart.

From the Pythagorean Triplets (5,12,13) :

The shortest side is the base of the right triangle.

Therefore, Base = 5 meters.

Melissa and her younger sister are 5 meters apart.
