Question

The angle whose sine is 0.39581 is

Answer 1

Answer:

The angle whose sine is 0.39581 is 23.31°.

Step-by-step explanation:

Given : Sine is 0.39581

To find : The angle whose sine is 0.39581 is ?

Solution :

Let x be the angle of sin whose value is given,

i.e. $\sin x=0.395821$

Now, we can write this as

$x=\sin^{-1}0.395821$

Now, using calculator we find the value of $\sin^{-1}0.395821$ in degree.

$x=\sin^{-1}0.395821$

$x=23.31^\circ$

Therefore, The angle whose sine is 0.39581 is 23.31°.

Answer 2

The angle whose sine is 0.39581 is 23.31650126° (round it how you want). 
To calculate this, you need to do the inverse sine of 0.39581. 

Inverse sine looks like $sin^{-1}$, however, it is not the sine of the angle to the power of -1.
