Please help. I've been working on this problem for more than 2 hours. Thank you. three support beams for a bridge form a pair of complementary angles. Find the measure of each angle.

Ametal rod needs to be 9 feet and 5.5 inches in length. the sections of the poles being used are each 1 foot and 10.5 inches long. how many 1ft 10.5in sections would be needed to complete the 9ft 5.5in metal rod? and how many inches of material will be left?
