Question

Can pls help me with my homework plss

Answer 1

Who good with algebra 2?

Answer 2

`cos \: k = (adj)/(hyp) = (5)/(13)`

//

I'm unsure about what to do after that but you can:

`cos( (5)/(13) ) = 0.999977469`

`cos \: k = 1.00`

or

`(5)/(13) = 0.384615385`

`= 0.38`

I think the first one's safer.
