## How to Use the Sine Calculator?

The procedure to use the sine calculator is as follows:

Step 1: Enter the opposite side and hypotenuse side of the right triangle in the input field

Step 2: Now click the button “Solve” to get the angle

Step 3: Finally, the sine angle of the right triangle will be displayed in the output field

### What is Meant by Sine Angle?

In trigonometry, the sine function is one of the six important trigonometric functions. In a right triangle, the sine angle or the sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse. If θ is the angle, then the sine angle is given by the formula

Sin θ = Length of the opposite side / Length of the hypotenuse

Here,

The opposite side is opposite to the angle θ

The adjacent side is the side next to the angle θ

The hypotenuse is the longest side of the right triangle
