Civil Engineering problem ( highway Geometry - Spiral Curves )

 I need an answer in 4 hours. please don't place a bid if you can't provide an answer in 4 hours. 

 

Question1: It is desired to stake out a 300-ft spiral curve for transition into a 4°0000" circular curve (arc definition). The PI is at station 70+00 and the intersection angle I has been measured and found to be 50°0000". Compute the deflection angles and chords (i.c. stake out notes) for staking out the curve at 50-ft stations.

Qucstion 2 : For the spiral curve in Question, compute the long chord (L.C), long tangent (L.T), short tangent (ST) and the spiral tangent length (T)

Question 3 : For the spiral curve in Question 1, compute the deflection angles and chords (i.e., stake out notes) for staking out the curve if the spiral is divided into 5 equal chords.

please do not copy the answer from a different question because the numbers here are different
