Sine Formula
About Sine Formula
The sine formula is used to compute the angle of a right-angled triangle. This formula shows the relationship between the sides and angles of a right angle. The ratio of the opposing side to the hypotenuse side of a right triangle is known as sine. The hypotenuse is the longest side, while the opposite side is the opposite side of the hypotenuse. Sin is the shorthand for sine function in trigonometry.
The Sine Angle Formula is, sinθ = 
Solved examples of Sine Formula
Example: Calculate the sine angle of a right triangle whose opposite side and hypotenuse are 10 cm and 12 cm respectively.
Sol: It is given that Opposite side = 10 cm Hypotenuse = 12 cm
Using the formula: sinθ =
sinθ = 
sinθ = 0.83
