If t=38.5 and s=31.4 find S. Round to the nearest tenth
zubka84 [21]

<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°
