Question 1:

The point of tangency is located at 29+64.247from method 1
The point of tangency is located at 29+69.93 from method 2
However if we see nearest figure from the given options,
The correct option is A. 29 + 61.4

Calculation:
R = 5729.58 / D
T = R * tan ( A/2 )
L = 100 * ( A/D )
LC = 2 * R *sin (A/2)
E = R ( (1/(cos (A/2) ) ) - 1 ) )
M = R ( 1 - cos (A/2) )
PC = PI - T
PT = PC + L
D = Degree of Curve, Arc Definition
1° = 1 Degree of Curve
2° = 2 Degrees of Curve
P.C. = Point of Curve
P.T. = Point of Tangent
P.I. = Point of Intersection
A = Intersection Angle, Angle between two tangents
L = Length of Curve, from P.C. to P.T.
T = Tangent Distance
E = External Distance
R = Radius
L.C. = Length of Long Chord
M = Length of Middle Ordinate...
