Answer:
Angle is 37.21 degree
Step-by-step explanation:
Given Data
|A|=2.93
|B|=3.00
A×B=-4.95k+1.94i
Angle=?
Solution
|A×B|=|A|×|B|Sinα
First for |A×B|
|A×B|=[tex]\sqrt{x^{2}+y^{2} }[/tex]
|A×B|=[tex]\sqrt{(-4.95)^{2}+(1.94)^{2} }[/tex]
|A×B|=5.316
|A×B|=|A|×|B|Sinα
Sinα=[tex]\frac{|A*B|}{|A||B|}[/tex]
Sinα=[tex]\frac{5.316}{8.79}[/tex]
α=37.21 degree
