Question

I need help! Express cos U as a fraction in simplest terms.

Answer 1

cos(U) = 0.4

Step-by-step explanation:

`\sf cos(U)= (adjacent)/(hypotensue)`

given:

• adjacent: 4

• hypotenuse: 10

using formula:

`\rightarrow \sf cos(U)= (4)/(10)`

`\rightarrow \sf cos(U)= (2)/(5)`

`\rightarrow \sf cos(U)= 0.4`
