F1 = 75.0 Newtons, 25 degrees east of north

F2 = 100 Newtons 25 degrees east of south

i drew a picture again

I took the for F1 sin 25 * 75 and got 31.69

F2 cos 25 * 75 and got 67.97

Sin 25 * 100 = 42.67

cos 25 * 100 = 90.63

So then i added the 31.69+(-42.67) = -10.98

and added 67.97+90.63 = 158.60

used the C^2 = A^2 + b^2 C^2 =158.60^2+10.98^2

C = 158.98 N

Tan -1 (158.60/-10.98)

and theata was = to a -86.04 degrees east of south

is that one right??????
