Answer 1

¡Hola!

Para ángulo $\beta$

a= 3

c= 5

b=4

Sabiendo esto resolvemos.

$\cos(\beta)=\dfrac{b}{c} \\\\ \Rightarrow \boxed{\boxed{\cos(\beta)=\dfrac{4}{5}}}$

$\tan(\beta)=\dfrac{a}{b} \\\\ \Rightarrow \boxed{\boxed{ \tan(\beta) =\dfrac{3}{4} }}$

Para ángulo y.

$\csc (y)=\dfrac{c}{b} \\\\ \Rightarrow \boxed{\boxed{ \csc(y)=\dfrac{5}{4}}}$

$\sec(y)=\dfrac{c}{a} \\\\ \Rightarrow \boxed{\boxed{ \sec(y)=\dfrac{5}{3} }}$

$\cot(y)= \dfrac{a}{b} \\\\ \Rightarrow \boxed{\boxed{ \cot(y)=\dfrac{3}{4}}}$

Espero que sirva y saludos.
