How to find the value

x = 4°

Step-by-step explanation:

According to exterior angle sum property , sum of two opposite interior angles of the triangle is equal to the exterior angle.

So, using exterior angle sum property :-

mBDC + mBCD = mWBC

=> 8x - 1 + 46° = 18x + 5

=> 18x - 8x = 46 - 1 - 5

=> 10x = 40

=> x = 4°

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°
