In the rhombus, m∠1 = 10x, m∠2 = x + y, and m∠3 = 3z. Find the value of each variable. The image is of a rhombus with diagonals. Angles made at the intersection of diagonals are marked as 1, 2 and 3 at bottom right, bottom left and top left respectively.

A. x = 9, y = 81, z = 30
B. x = 18, y = 171, z = 30
C. x = 18, y = 81, z = 60
D. x = 9, y = 171, z = 60

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
