Answer: 2900185 Joules
Step-by-step explanation:
Force used to tow the car is 1600N
Angle(α)= 25
Displacement = 2km
Recall that 1km= 1000m
Therefore 2km= 2000m
Workdone= FdCos α
 W= 1600 * 2000 * cos 25
 W=2900184.919
 W= 2900185 Nm(when approximated to the nearest integer) 
Since 1J = 1Nm
Work done = 2900185 J
 
        
             
        
        
        
Answer:
The value of angle B is 33.69°
Step-by-step explanation:
You can find out using Tangent Rule, tanθ = oppo./adj. where opposite and adjacent are the length of triangle :
oppo. = AC = 6 units
adj. = BC = 9 units
θ = ∠B
tan ∠B = AC/BC
tan ∠B = 6/9
∠B = tan^(-1) (6/9)
 = 33.69° (near. hundredth)
