Compute the amount of metal bar stock required to fram 3'73 450 The below image is a schematic for a frame of a simply constructed utility trailer. a) What is the square footage of the trailer floor? 4'6" 6'8- 5'7-" 3'5" b) Calculate the amount of bar stock required to build the trailer frame, including all corner supports (all 10 pieces). Solve the below trigonometry problems, stating your answers in feet, inches and fractions of an inch, rounded to the nearest 16th of an inch where necessary. 1. Solve for each of the missing angles and sides. A = 30.250 a = B = b = 27 8 C =90 c = 2. Solve for each of the missing angles and sides. A = a =2'2 -3" 16 B = b = C =90 c = 3'8-"
