I’ve tried calculating it on my own but I’m not getting a degree even close to the answers?

Below

Step-by-step explanation:

You need to use SOH CAH TOA to find theta.

Looking at the triangle, we have the opposite side which is 9 and the adjacent side which is 10. This means you have to use Tangent to find theta.

Tan θ = opposite/adjacent

Tan θ = 9 / 10

       θ = tan inverse ( 9 / 10 )

       θ = 41.98

       θ = 42 degrees

i dont know answer:

step-by-step explanation:

it would be 6xy and -16xy.
