A) remains same
B) doubles the original lengthy
C) become three times the original length
D) become half of the original length
Correct Answer: B
Solution :
Given \[AB=2\times 4=8ft\] |
\[\therefore \] In \[\Delta ABC,\] \[\sin 30{}^\circ =\frac{AB}{AC}\Rightarrow \frac{1}{2}=\frac{8}{AC}\,\Rightarrow AC=16\] |
So, AC doubles the original length. |
So, option [b] is correct. |
