Answer:
A. 4
Explanation:
Use the law of sines to solve:
![(sin 90)/(8)=(sin30)/(x) \\x=8sin30\\x=4](https://img.qammunity.org/2023/formulas/mathematics/high-school/ujojo76gzu9pj1qh8zp36i0or38r66tzki.png)
Alternate method: use properties of 30-60-90 triangle:
If the hypotenuse of a 30-60-90 triangle has a length of x, then the shortest leg has a measure of
.
Substitute x and you will get 4 as your answer.
