[tex]Sin=\frac{Opposite}{Hypotenuse} Cos=\frac{Adjacent}{Hypotenuse} Tan=\frac{Opposite}{Adjacent}[/tex]
7) You have the opposite. You need the adjacent.
[tex]Tan=\frac{Opposite}{Adjacent}[/tex]
[tex]Tan57=\frac{12}{x}[/tex]
[tex]x=\frac{12}{Tan57}[/tex]
x = 7.79289... =
7.8
8) You have the hypotenuse. You need the Opposite.
[tex]Sin=\frac{x}{Hypotenuse}[/tex]
[tex]Sin37=\frac{x}{13}[/tex]
x = sin37 × 13
x = 7.8235... =
7.8
9) You have the hypotenuse. You need the opposite.
[tex]Sin=\frac{x}{Hypotenuse}[/tex]
[tex]Sin59=\frac{x}{11}[/tex]
x = sin59 × 11
x = 9.4288.... =
9.4
10) You have the hypotenuse. You need the opposite.
[tex]Sin=\frac{x}{Hypotenuse}[/tex]
[tex]Sin53=\frac{x}{11}[/tex]
x = sin53 × 11
x = 8.7459.... =
