How Can We Find The Value Of Sin A in a Triangle ABC?

Solution:

In trigonometry, the sine of an angle in a right triangle is a ratio defined as given below.

The Sine of some angle A, written as Sin A, is the ratio of the opposite side (opposite to angle A) to the hypotenuse in the triangle.

Sin A = $\frac{oppositev\ side}{hypotenuse}$

The sine of some common angles has values shown as follows

Sin 0 = 0; 

Sin 30 = $\frac{1}{2}$

Sin 45 = $\frac{1}{\sqrt 2}$

Sin 90 = 1 and so on
