Sin 30°= Perpendicular Hypotenuse Sin 30°= XY / XZ On substituting the value of sin 30 ½ = XY/ XZ ½ = 10/ XZ XZ = 20cm Therefore, the length of the side, XZ = 20 cm. Example 2: How do I find the value of sin(-30)? Solution: Sin (-30) = – Sin (30) Sin 30...
Sine, cosine and tangent are the three main pillars on which the whole concept of trigonometry rests. Sin is one of those important trigonometric ratios. The value of sin 30 degrees is half (½). Just to recapitulate the sides of a triangle, let's go through the following definitions on...
