FUNDAMENTALS OF SURVEYING SAMPLE QUESTIONS wn in the 5. The two survey lines on the figure are represented mathematically by two equations: 1. E - EL = tan 450 N - N 2. E - E2 = tan 3150 - N - N 2 What is the correct equation for the east coordinate of the point of intersection? (A) E = N2 - NI - E, E, N m E : (B) E = N - N2 2( E + E2) AZ = 45' Az = 315 N + N 2 (C) E = E + E2 (D) E = 1/2 [(E, + E2) -(N, - N2)] N1 N2
