Question

What is the area of triangle ABC?

Answer 1

`\circ\ \ 36√(3)`

Explanation:

`CD=12* \sin(60) =12* (√(3) )/(2)`

Important Note:………………………………………………………………………………………

ABC is an equilateral triangle because it has 2 angles of measure 60

===========================================================

According to the note AB = 12

Final answer :

`\text{Area of triangle ABC} =(AB* CD)/(2)`

`=(12* 6√(3) )/(2)`

`=(72√(3) )/(2)`

`=36√(3)`
