4. Given U <2, 1, 1>, V=<2, -1, -3> and W=<-4, 7, -5>, which of the following pairs is (are) perpendicular? Circle your answers. Clearly show how you arrived at the result: U and V U and W V and W 5. A triangular brace has to be fabricated for a custom building frame. Two main beams of the brace need to be welded prior to installation. In the graphs, the beams are shown in red and the brace is blue. In the design environment for the frame (in a coordinate system), these two main beams. will extend from the point O(6,5,3) to the points 4(5,-2,7) and B(-2,8,5). a. How long, to the nearest 0.1 ft, is the brace that will extend from A to B? 文艺 b. At what angle should the two beams be welded (to the nearest 0.1°)?
