WILL GIVE A BRAINLEST AND 15PTS

Which equations for the measures of the unknown angles x and y are correct? Check all that apply.


x = cos–1(a/c)


x = sin–1(c/b)


x = tan–1(c/a)


y = sin–1(a/c)


y = cos–1(c/b)

we know that

In the right triangle of the figure

For the angle x

[tex]cos(x)=\frac{a}{b}[/tex]

[tex]x=cos^{-1}(\frac{a}{b})[/tex]

[tex]sin(x)=\frac{c}{b}[/tex]

[tex]x=sin^{-1}(\frac{c}{b})[/tex]

[tex]tan(x)=\frac{c}{a}[/tex]

[tex]x=tan^{-1}(\frac{c}{a})[/tex]

For the angle y

[tex]cos(y)=\frac{c}{b}[/tex]

[tex]y=cos^{-1}(\frac{c}{b})[/tex]

[tex]sin(y)=\frac{a}{b}[/tex]

[tex]y=sin^{-1}(\frac{a}{b})[/tex]

[tex]tan(y)=\frac{a}{c}[/tex]

[tex]y=tan^{-1}(\frac{a}{c})[/tex]

therefore

the answer is

[tex]x=sin^{-1}(\frac{c}{b})[/tex]

[tex]x=tan^{-1}(\frac{c}{a})[/tex]

[tex]y=cos^{-1}(\frac{c}{b})[/tex]
