Question

Express the cosine of angle U as a ratio of the given side lengths

A) 12/13

B) 13/12

C) 5/12

D) 5/13

Answer 1

D. 5/13

Explanation:

Answer 2

Option A)
`12/13`

Explanation:

we know that

The cosine of angle U is equal to divide the adjacent side to angle U (UV) by the hypotenuse of the right triangle (UW)

so

`cos(U)=(UV)/(UW)`

substitute the given values

`cos(U)=(12)/(13)`
