The following designs use different amounts of materials for their support structures. • Each design incorporates a horizontal distance of 1,400 feet of road. • Each design contains two congruent triangles for bridge supports 1. Find the amount of support materials (colored in the diagrams) needed for each design. Round all lengths to the nearest whole number. You may find it necessary to use any or all of the following tools: Supplementary Angle Properties Triangle Sum Theorem Pythagorean Theorem Right Triangle Trig (SOHCAHTOA) 30-60-90 Triangle Properties 45-45-90 Triangle Properties Law of Sines Law of Cosines Please include the cost and how much material.
