Problem
Two railway tracks are planned to be laid perfectly parallel. During construction, an engineer places a straight steel girder t across the tracks to keep them at the correct distance. The girder meets the first track at an angle of 125∘ on the exterior, west side. Based on this information, answer the following parts.
(i) Calculate the corresponding angle formed between the girder and the second track on the west side.
(ii) Determine the interior angle between the girder and the second track on the east side.
(iii) Find the acute angle between the girder and the first track on the east side.
