Answer:
Well you know that
sin X=Op/Hip
cos X=Ady/Hip
tan X=Op/Ady
so the first one
[tex]sin(A)=\frac{9}{\sqrt{90} } =\frac{3\sqrt{10} }{10}[/tex]
[tex]cos(A)=\frac{3}{\sqrt{90} } =\frac{\sqrt{10} }{10}[/tex]
[tex]tan(A)=\frac{9}{3} =3[/tex]
the second
[tex]sin(C)=\frac{5}{7}[/tex]
the third
[tex]cos(X)=\frac{18}{9\sqrt{5} } =\frac{2\sqrt{5} }{5}[/tex]
the fourth
[tex]sin(B)=\frac{8}{10} =\frac{4}{5}[/tex]
the fifth
[tex]tan(34)=\frac{x}{29}[/tex]
[tex]x=tan(34)*29=19.56[/tex] aprox.
