In a right angle triangle the three sides are represented by the letters a, b and c .
a represents the side adjacent with given angle .
b represents the side opposite to the given angle.
c represents the hypotenuse of the triangle .
Check the attached image for clear picture of the right angle triangle with angle 30 degrees .
Using the trigonometric ratio we can write the ratio as
[tex]\frac{b}{a} = tan(30^0)[/tex]
Multiplying both sides by a , we get
[tex]b =a * tan(30^0)[/tex]
since a=8 so
[tex]b = 8* tan(30^0)[/tex]
