Question

Quizás quisiste decir: The equation sin (40 degree) equals StartFraction b Over 20 EndFraction can be used to determine the length of line segment AC.What is the length of ? Round to the nearest tenth.

Answer 1

Step-by-step explanation:

`\sin 40º=(b)/(20)`

We have to solve for b, by multiplying both sides by 20:

`b=20\sin 40º=12.85575219`

Answer:

Rounded to the nearest tenth, the length of the segment is 12.9 cm
