PLEASE HELP! ITS DUE SOON!!!! I DONT GET THIS!!!

Answer 1

I am very sorry to say but I can't help you with these

Answer 2

d. 50°

Using Sine rule:

`\sf (sin(A))/(a) = (sin(B))/(b)`

Insert the values:

`\rightarrow \sf (sin(36))/(11.9) = (sin(D))/(15.6)`

`\rightarrow \sf sin(D) = (15.6 \ sin(36))/(11.9)`

`\rightarrow \sf sin(D) = 0.770542`

`\rightarrow \sf D = sin^(-1)(0.770542) = 50.4 \quad \approx \quad 50^(\circ \:)`
