Answer:
48% of 25 is 12.
Step-by-step explanation:
To find : what percent of 25 is 12?
Solution : Let x be the percentage of 25 which is 12
So, by the statement
x% of 25 = 12
Now, we have to calculate the value of x
Step 1- Write the expression
Step 2- divide 25 by 100
Step 3- Cross multiply
Therefore, 48% of 25 is 12.
First, we are going to add 
from both sides of the equation:
Next, we are going to use the trig identity:
to rewrite our expression:
Finally, using our unitary circle, we can infer that
from 0 to 
when 
and 
We can conclude that the solutions of the equation <span>cos (x) tan (x) -1/2=0 over the interval [0,2π] are: </span>
