The fraction is expressed as tan J = 4/3
Trigonometric Identities are useful whenever trigonometric functions are involved in an expression or an equation. Trigonometric Identities are true for every value of variables occurring on both sides of an equation.
Geometrically, these identities involve certain trigonometric functions (such as sine, cosine, tangent) of one or more angles.
The tangent identity ratio is given as;
tan = opposite/adjacent
substitute the values, we have;
tan J = 16/12
Divide the values, we have;
tan J = 8/6 = 4/3
