Answers;
let a horizontal line parallel to X-Axis be drawn at the tip of d1.
Angle between the vector and the line = 180 - 26.5 = 153.5
Angle between the line and the boy = 2 = 131
So total angle between the 2 vectors = = 131 + 153.5 =
284.5 degrees
Resultant = R = sqrt( P^2 + Q^2 + 2*P*Q*cos )
R = sqrt ( 24^2 + 11.5^2 + 2*24*11.5*cos284.5 )
= sqrt ( 846.4597)
= 29.094 m (Answer)
Let the horizontal distance between O and d1 be y
d1 * cos(1) = y
y = 24 * cos (26.5)
= 21.478 m
Again horizontal distance between d2 and d1
= d2*sin ( 131 - 90)
= 11.5 * sin 41
= 7.545 m
Difference = 13.934 m
If the angle between base and resultant is x
cos (x) = 13.934 / 29.094
= 0.4789
x = 61.385 degrees ( Answer)
