Question

What is the exact side length of DB given triangle ABC ?

Answer 1

Given:

There are given that the equilateral triangle ABC.

Step-by-step explanation:

In the question, there are given equilateral triangles.

So,

From the concept of the equilateral triangle:

The equilateral triangle defines when all three sides are equal and all three angles are 60 degrees.

Then,

In the given triangle ABC,:

`\begin{gathered} AB=12 \\ AC=12 \\ BC=12 \end{gathered}`

So,

For finding the value of DB:

`\begin{gathered} AB=12 \\ AD=(12)/(2) \\ DB=(12)/(2) \\ =6 \end{gathered}`

Final answer:

Hence, the side length of DB is 6.
