A cyclist travels 5 miles in the direction N 30° E, then travels 3 miles in the direction N 70° E. Which equation measures the cyclist's distance, x, from the starting point?

52 = x2 + 32 – 2(3)(x)cos(100)
52 = x2 + 32 – 2(3)(x)cos(140)
x2 = 52 + 32 – 2(5)(3)cos(100)
x2 = 52 + 32 - 2(5)(3)cos(140)
