[Thinking] [10 Marks] 3. Three vectors ii, 3, and 13' have magnitudes Il = 12, IBI = 16, and Il = 26.1f131ies between (i and E in the same plane, making an angle of 20 with (i and 30 with B. The vector diagram is shown. [5] a) Find the resolutions of vector (i, 3, and 13 into x and y directions. v _) 13 b 30\" 20 x a b) Use the vector components found from a) to express 13 as a linear combination of (i and 3
