What is the easiest to understand formula for solving 30 60 90 special right triangles?

Marianna [84]

Step-by-step explanation:

30°, 60°, 90° triangle theorem states that:

Lengths of the side opposite to 60° angle is equal to root 3 upon two times of the length of hypotenuse and side opposite to 30° angle is equal to 1 upon two times of the length of hypotenuse.

Mathematically it can be expressed as:

$Length \: of \: sides \: opposite \: to \: 60 \degree \: \\ angle \\ = \frac{ \sqrt{3} }{ {2} } \times length \: of \: hypotenuse.\\\\Length \: of \: sides \: opposite \: to \: 30 \degree \: \\ angle \\ = \frac{1}{ {2} } \times length \: of \: hypotenuse.\\\\$
