Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
k = −1
b×h=a
this is how to represent it and it is a direct variation.
In this question , we have to find the value of tan 30 and we need to write the answer in simplified form .

Substituting the values of sin (30) and cos(30, we will get

Multiplying both numerator and denominator by 2, we will get

TO simplify it, we need to multiply both numerator and denominator by square root 3.
