Two forces 60n and 80n respectively act simultaneously at a point

Answer 1

so you get somewhere between 20 and 140 N depending on the angles which you do not tell us.

Answer 2

Assumption:
F1 = 60N. @ 0o. =
F2 = 80N @ 90o.

Fr = Sqrt(60^2 + 80^2) = 100N. = Resultant force.
TanA = F2/F1 = 80/60.
A = 53.1o = Direction.
