Answer:
Rounded to nearest hundredths is 8.75.
Rounded to nearest tenths is 8.7.
Step-by-step explanation:
Law of sines:
[tex]\frac{\sin(A)}{\text{ side opposite to }A}=\frac{\sin(B)}{ \text{ side opposite to }B}[/tex]
Measure of angle [tex]A[/tex] is 28 and the side opposite to it is [tex]x[/tex].
Measure of angle [tex]B[/tex] is 105 and the side opposite to it is 18.
Plug in to the formula giving:
[tex]\frac{\sin(28)}{x}=\frac{\sin(105)}{18}[/tex]
Cross multiply:
[tex]18 \sin(28)=x \sin(105)[/tex]
Divide both sides by sin(105):
[tex]\frac{18 \sin(28)}{\sin(105)}=x[/tex] is the exact answer.
I'm going to type it in my calculator now:
18*sin(28) / sin(105) is what is going in there.
The output is 8.748589074.
Rounded to nearest hundredths is 8.75.
Rounded to nearest tenths is 8.7.
