Two forces act on an object at an angle of 75 degrees.1 force is 195N.The resultant force is 225N.Determine the second force and the angle that it makes with the resultant.

Whether both the forces are acting at an angle 75 degree?. If yes the second force is 30N.
If not, you have to tell at which angle you are getting the resultant.

What exactly do you mean by 'at an angle of 75 degrees'?? There are many possibilities unless you are more specific.

just use law of sines - A/sina=B/sinb=C/sinc
it would be an SSA
third force turns out to be 173.54N
the angle turns out to be 56.84 degrees

would desire to locate sum of forces interior the x-instructions and then interior the y-instructions. Then use those to get the magnitude, then the attitude. sum of x is x1 + x2 = 25cos(71) + 18cos(fifty 3). forces in comparable course (west) Sum of y is y1 +2 = 25sin(71)+ -18sin(fifty 3). forces in opposite course (north/south) You get Sum(x) = 18.ninety seven west and Sum(y) = 9.26 north. pythag yields magazine of 21.eleven making use of sum(x) and sum(y) Yields Tan(attitude) = 9.26/18.ninety seven, attitude is 26 stages norrth of west.
