The expression of refractive index of a prism is given by the following relation : u= sin( A+D/2 )÷sin( A/2 ) Assuming the error of A and D as ∆A and ∆D express the error of u . Here 'A' is the angle of the prism and 'D ' is the angle of deviation

Physics

R_x = A_x + B_x + C_x

A_x is negative as the vector is in third quadrant.

B_x is positive as it points in the first quadrant.

C_x is positive as it points in the fourth quadrant.

Hence,

R_x = -1.6 + 3.9 + 1.2

R_x = 3.5 km

R_y = A_y + B_y + C_y

A_y is negative as it is in third quadrant.

B_y is positive as it is in first quadrant.

C_y is negative as it is in fourth quadrant.

R_y = -2.8 + 6.4 - 0.7

R_y = 2.9 km
