Two street curb lines intersect with Δ = 71°36 (see Figure 11.33). A curb radius must be selected so that an existing catch basin (CB) will abut the future curb. The curb side of the catch basin cL is located from point V: V to CB = 8.713 m and angle E-V-CB= 21°41. Compute the radius that will permit the curb to abut the existing catch basin.
