Sight Triangle

Using the equations and tables below from the AASHTO Green Book, solve the question:

A single$-$unit truck is turning left from a minor road onto a two$-$lane major road. The design speed of the minor road is $35mph.$ The design speed of the major road is $55mph.$ The intersection is level.

What is the corresponding intersection sight distance, in feet?
