Answer:

[tex] \cos \beta = \dfrac{8}{17} [/tex]

Step-by-step explanation:

[tex] \cos A = \dfrac{adj}{hyp} [/tex]

For angle beta, adj = BC = 8, and hyp = AB = 17

[tex] \cos \beta = \dfrac{adj}{hyp} [/tex]

[tex] \cos \beta = \dfrac{BC}{AB} [/tex]

[tex] \cos \beta = \dfrac{8}{17} [/tex]

Answer:

Cos B = 8/17

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos B = adjacent/ hypotenuse

Cos B = 8/17
