Hello. Let me explain

Step-by-step explanation:

Line I: y=4

Line m:y=-2x+4

Line n: y=x-1

If you want more information tell me so i can edit the answer.

For finding the slope of each line use this formula:

m= y2-y1/x2-x1

You need two points which are on each line.

After finding slope this is the formula for line

y2-y1=m(x2-x1)

If you use this two formulas you can find each line equation.

Hope you understand.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
