<u>Answer:</u>

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

<u>Step-by-step explanation:</u>

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

We are to find the value of the angle S.

For that, we will use sine.

sin S = \frac { s } { t }

sin S = \frac { 3 1 . 4 } { 3 8 . 5 }

S = sin'0.815

S = 54.6°

Answer: option c.

Step-by-step explanation:

You need to remember the identity:

sin\alpha=\frac{opposite}{hypotenuse}

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

 \alpha =arcsin(\frac{opposite}{hypotenuse})

You know that you need to find the measure of "S" and t=38.5 (which is the hypotenuse) and s=31.4 (which is the opposite side), then you can substitute values into   \alpha =arcsin(\frac{opposite}{hypotenuse})

Then, you get:

S=arcsin(\frac{31.4}{38.5})\\\\S=54.6\°
