Two forces are acting at a point make angle of 25 and 65 respectively with their resultant which is of magnitude 15N.Find the magnitude of two components forces

Answer 1

Say resultant is in x direction
A at +25 and B at -65
so
Rx = 15 and Ry = 0
and
Rx = A cos 25 + B cos 65 = 15
Ry = A sin 25 - B sin 65 = 0
solve for A and B

Answer 2

Solve

Answer 3

Fx = 15cos25 = 13.6N
Ft = 15sin65 = 13.6N
