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

Short Answer

The lengths of two vectors a and b, and the angle  between them, are given. Find the length of their cross product, $| \mathbf { a } \times \mathbf { b } |$
. Write the answer correct to three decimal places. $| \mathbf { a } | = 0.12 , \mathbf { b } \mid = 1.25 , \theta = 85 ^ { \circ }$
