Math Problem Statement
There are 3 vectors in a 2D coordinate with unit vector 𝑥̂ and 𝑦̂ along x and y axes respectively. The magnitude of 𝑎⃗ is 5 and it forms an angle of 60𝑜 with the positive x-axis. Vector 𝑏⃗⃗ = 5𝑥̂ + 8𝑦̂. The coordinates of the starting and ending points of 𝑐⃗ are (4, 5) and (12, 7). Calculate the resultant of 𝑎⃗ + 𝑏⃗⃗ + 𝑐⃗
