Question

) If the acute angle of right angled triangle are 30 and 60 , then length of side opposite to 30 is.................. hypotenuse *​

Answer 1

Answer:

The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle. And, finally, the side opposite the 90° angle will always be the largest side (the hypotenuse) because 90 degrees is the largest angle.

Answer 2

Step-by-step explanation:

Given:

Right-angled Δ$ABC$ has three angles $30^{o} , 60^{o}$ and $90^{o}$.

To find: length of side $BC$

Calculation:

From the figure,

$sin30^{0} =\frac{BC}{AC} \\\frac{1}{2} =\frac{BC}{AC}\\AC=2BC$

Hypotenuse of the triangle is $AC$.

Side of length opposite to 30 is $BC$ which is $\frac{AC}{2}$.

Answer:

Side of length opposite to $30^{o}$ is half the hypotenuse.
