The picture. and answer 1-6. please hurry

Step-by-step explanation:

From the figure attached,

1). Sin(D) =

               =

               =

               =

2). Cos(D) =

                =

                =

                =

3). tan(D) =

               =

               =

               =

4). sin(F) =

              =

              =

              =

5). cos(F) =

               =

               =

               =

6). tan(F) =

               =

               =

               =

m∠a is 90°

m∠b is 40°

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
