Question

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!! I NEED TO FINISH THESE QUESTIONS BEFORE MIDNIGHT TONIGHT.

Answer 1

Answer:

The answer to your question is QS = 5

Step-by-step explanation:

Data

hypotenuse = RQ = 8

angle = 39°

Opposite side = QS = ?

To solve this problem use trigonometric functions. The trigonometric function that relates the opposite side to hypotenuse is sine.

               sin α = $\frac{opposite side}{hypotenuse}$

Solve for opposite side

               Opposite side = hypotenuse x sin α

Substitution

               Opposite side = 8 sin 39

Simplification

                Opposite side = 8(0.63)

Result

                Opposite side = 5.0

Answer 2

Answer: QS= 4.93

Step-by-step explanation: because they’re asking you to find QS which is opposite to your angle 39and we have the hypotenuse so we can use sine(39)=x/8.

Sin(39)=x/8

Multiply eight both side

8(sin(39))=x

4.93=x

X=4.93
