Samantha and juan share a pie equally. Samantha eats 1/2 of her share. What fraction of the whole pie did she eat? Select all th
GenaCL600 [577]
Since it’s two people the pie would be divided by two. So if she ate half of a half, I’m guessing the answer would be 1/4.

Find the length of side x in simplest radical form with a rational denominator
Angelina_Jolie [31]

Answer:

The length of x=3/1

Step-by-step explanation:

Given the right triangle

Ф = 30

We know that

sin Ф = opposite/hypotenuse

The opposite of angle 30° = x

The hypotenuse is = 6

so

sin 30 = opposite/hypotenuse

    1/2      = x/6           ∵ sin 30 = 1/2

     1/2 × 6 = x

     6/2 = x

       3/1 = x

Therefore, the length of x=3/1
