<h3>What are Trigonometric functions?</h3>
The trigonometric function gives the ratio of different sides of a right-angle triangle.
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.
The value of c can be found by using the cosine function of trigonometry, therefore, the value of b is,
Cos(19°) = 48/b
b = 48/Cos(19°)
b = 50.76579 ≈ 50.76 units
Hence, the value of b is 50.76 units.
