If t=38.5 and s=31.4 find s. round to the nearest tenth

The correct answer option is C. S = 54.6°.

Step-by-step explanation:

We are given a right angled triangle with two known sides, and .

We are to find the value of the angle .

For that, we will use sine.

S = 54.6°

option c.

Step-by-step explanation:

You need to remember the identity:

The inverse of the sine function is arcsine. You need to use this to calculate the angle "S":

You know that you need to find the measure of "S" and (which is the hypotenuse) and (which is the opposite side), then you can substitute values into   

Then, you get:

why can't you?

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!
