The force A = 4.0N makes an angle of 30° above the positive x-axis. The force B = 6.0N makes an angle of 50° above the negative x-axis. The force C = 8.0N
makes an angle of 45° below the positive x-axis. Find the magnitude and
direction of the vector sum of these three forces.

a.) is the correct answer.

explanation:

2b2t

explanation:

2b2t

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
