Given:

\frac{2tanx}{1-tan^2(x)} =\sqrt{3}

We know the identity

tan(2x)= \frac{2tanx}{1-tan^2(x)}

So we can equate tan(2x) =\sqrt{3}

tan(x) =\sqrt{3} when x=\frac{\pi}{3}

Tan is positive in first and third quadrant

So we will get one move value for x

tan(x) =\sqrt{3} when x=\frac{4\pi}{3}

So for  tan(2x) =\sqrt{3}

2x=\frac{4\pi}{3}  and 2x=\frac{\pi}{3}

Divide by 2 on both sides

x=\frac{2\pi}{3}  and 2x=\frac{\pi}{6}

To get general solution we add n\pi

So option A  and option C are correct.

On a number line, A is at 5 and B is at 50. Point X is the midpoint. Point T is 2/3 of the way from X to B. Determine the coordi
Lemur [1.5K]

Number lines are used to represent points at regular interval.

The coordinate of point T on the number line is: 46.5

Given that:

A =5

B = 50

The coordinate of X at the midpoint is:

X = \frac{B + A}{2}

So, we have:

X = \frac{50+5}{2}

X = \frac{55}{2}

X = 27.5

Point T is at 2/3 from X to B.

The coordinate of T is calculated using:

T = X + \frac 23 (B - X + 1)

So, we have:

T = 27.5 + \frac 23 (55 - 27.5 + 1)

T = 27.5 + \frac 23 (28.5)

T = 27.5 + 19

T = 46.5

<em>Hence, T is located at 46.5</em>
