What is the exact value of tan 30° ? enter your answer, as a simplified fraction, in the box?

attashe74 [19]

In this question , we have to find the value of tan 30 and we need to write the answer in simplified form .

$tan x = \frac{sin x}{ cos x}$

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

$tan (30) = \frac{1/2}{ \sqrt{3} /2}$

Multiplying both numerator and denominator by 2, we will get

$tan(30 ) = \frac{1}{ \sqrt3}$

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

$tan(30) = \frac{ \sqrt 3}{ \sqrt3 * \sqrt 3} = \frac{ \sqrt 3}{3}$

Naily [24]

Answer:

The total number of registered doctors was 167,722.

Step-by-step explanation:

Total number of doctors:

The total number of doctors is given by x.

31.6% of all registered doctors were female. 53,000 female doctors.

This means that:

$0.316x = 53000$

What was the total number of registered doctors?

We have to solve the above equation for x. So

$x = \frac{53000}{0.316}$

$x = 167722$

The total number of registered doctors was 167,722.
