The Lengths of Two Vectors a and B, and the Angle

question 8

Short Answer

The lengths of two vectors a and b, and the angle $\theta$ between them, are given. Find the length of their cross product, $| \mathbf { a } \times \mathbf { b } |$ . $| \mathbf { a } | = 0.12 , | \mathbf { b } | = 1.25 , \theta = 85 ^ { \circ }$
