I would want to round to the nearest hundred place rather than the nearest tens place because if you round to the nearest hundred place then your answer would be closer to the original answer.

If the sine of an angle equals to {2}/{5}, then the tangent of the angle could be:

Leona [35]

Answer:

If the sine of an angle equals to {2}/{5}, then the tangent of the angle could be:

5. $\frac{2}{\sqrt{21} }$

Step-by-step explanation:

Imagine a triangle

The sine of an angle is equal to the length of the opposite leg over the hypotenuse.
HINT: SOHCAHTOA

To find the adjacent leg (a):

Using the pythagorean theorem: $a^{2} + b^{2} =c^{2}$

- a and b are the lenght of the sides and c is the hypotenuse

we know one side and the hypotenuse. Therefore plugging into the formula we get:

$a^{2} + 2^{2} =5^{2}$

where a is the adjacent leg of the triangle, solving for a we get:

$a^{2} =5^{2}- 2^{2}$

$a^{2} = 21$

$a = \sqrt{21}$

To find the tangent of the angle:

Since tangent is opposite leg over the adjacent leg:

tan θ = $\frac{2}{\sqrt{21} }$
