Question

Solve the missing sides by using the trig function and choose a answer down below Answers for question:A. 29.3B. 36.3C. 16.8

Answer 1

Step-by-step explanation:

We can use the sine to solve this problem:

`\sin \alpha=(a)/(c)`

In this problem we have c = 31, alpha = 71 and a = x:

`\begin{gathered} \sin 71º=(x)/(31) \\ x=31\cdot\sin 71º \\ x=29.31 \end{gathered}`

Answer:

The correct answer is option A: x = 29.3
