Answer:
x = 16
Step-by-step explanation:
To solve the equation, we need to solve for x. Since it's being square-rooted right now, we need to square it (inverse operation of square root). Since we square one side, we also need to square the other to keep the equality:
The tangent of the given angles are the ratios <em>y</em> to the <em>x</em> coordinate of
the point of the terminal side on the unit circle.
The correct options are;
The tangent of an angle is given as follows;
First angle
An angle given is;
Therefore;
The above result can be obtained as follows;
Which is obtained when we have;
Therefore
The required coordinates is therefore;
Second angle
The angle, , gives;
The above value can be obtained as follows;
Which gives;
Third angle
The angle 210° gives; tan(210°) = , which can be obtained as follows;
Therefore;
