A triangular shade sail has sides of length 1 2 ′ 3 ″ and 1 5 ′ 6 ″ , and the angle between them is 73 ° 1 8 ′ . a. If the cost of the sail material is $ 8.75 / ft 2 , how much would this sail cost? Round to the nearest dollar. b. If the cost of wrapping the edges of the sail with a decorative border in a contrasting color is $ 125 / yd , what is the added cost to the sail? Round to the nearest dollar.

S.
where S, is the surface enclosing a cube centred at the origin and having edges of length 2€. Then,
determine if the origin is sink or source.
Let a = (-4, 5, 4) and 6 = (1,0, -1).
Find the angle between the vector
1) The exact angle is cos
2) The approximation in radians is
