In three dimensions, the cross product of two vectors is defined as shown below

Then, solving the determinant

In our case,

Where we used the formula for AxB to calculate ixj.
Finally,

Thus, (i+j)x(ixj)=i-j
Answer:cos(53), cos 53 degrees
Step-by-step explanation: sin(angle)= cos(90-angle)
sin(37)=cos(90-37)=cos(53)

Answer:
20.83 yard
Step-by-step explanation:
<u>Calculate Cubic Yards</u>
Calculate your area
Calculate your volume: Multiply area times the depth to get volume in cubic feet
Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer
Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard
Total yards = 5[x] + x + 8
<u>Solve</u>
133 = 6x + 8
6x = 125
x = 20.83 yard
Therefore, the Cyclone cleared 20.83 yards on the first day.
