Answer 1

Answer:

$\cos \beta = \dfrac{8}{17}$

Step-by-step explanation:

$\cos A = \dfrac{adj}{hyp}$

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

$\cos \beta = \dfrac{adj}{hyp}$

$\cos \beta = \dfrac{BC}{AB}$

$\cos \beta = \dfrac{8}{17}$

Answer 2

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
