answer and show work for question 8 only

Only do question 3

2. Vertical Curve Given the following vertical curve data, compute the elevations of the curve, including low/high point, and even 20m stations. Use either Tangent Offset or General Equation method. PVI @ 2+200 g1=-1% L=100m PVI El.=560.000 g2=1.5%

PROBLEM #2) A common tangent of a compound curve makes an angle of 12 degrees from the tangent passing through the PC and 18 degrees from the tangent passing through the PT. If the  radius of the second curve is 180m, find the radius of the first curve if the length of the common tangent is 70m long. (SIMPLE AND COMPOUND CURVES) *PLEASE USE THE FORMULAS BELOW*

Use the simplified version of the basic curve equation to calculate the minimum radius (ft) for a horizontal curve given a design speed of 60 mph, a maximum superelevation of 6.0% and a maximum friction factor of 0.12.

answer question 22 only

please make sure answer correct

The curved section of a highway in Southern California connects two tangents at station 20+75.00 at an angle A = 25°. The point of curvature is at station 16+50. a) Determine the radius of the existing curve. b) Determine the station of the point of tangency. . c) Does the radius of the given horizontal curve satisfy the minimum requirement based on AASHTO standards? Assume a design speed of 70 mph and emax = 10%. Support your answer.
