Answer:
B.) 7.2
Step-by-step explanation:
Use the sine ratio, [tex]sine=\frac{opposite}{hypotenuse}[/tex] , because we know the value of the hypotenuse and need to know the value opposite the given angle, 28°. Insert the values:
[tex]sin28=\frac{x}{15}[/tex]
Solve for x. Multiply both sides by 15 to isolate x:
[tex]15*(sin28)=15*(\frac{x}{15})\\\\15*sin28=x\\\\x=15*sin28[/tex]
Enter value into calculator:
[tex]x=7.042...[/tex]
Round to the nearest tenth:
[tex]x=7.0[/tex]
Option B is closest to the value of x.
Finito.
