If $\overrightarrow{A}=-4\hat{i}+3\hat{j}$  and $\overrightarrow{B}=2\hat{i}+5\hat{j}$ and $\overrightarrow{C}=\overrightarrow{A}\times \overrightarrow{B}$ , then the vector $\overrightarrow{C}$  makes an angle of

$\overrightarrow{A}=-4\hat{i}+3\hat{j}$ ,$\overrightarrow{B}=2\hat{i}+5\hat{j}$

$\overrightarrow{C}=\overrightarrow{A}\times \overrightarrow{B}$

     $=\left(-4\hat{i}+3\hat{j}\right)\times \left(2i+5j\right)$

     $=-20\hat{k}-6\hat{k}=-26\hat{k}$

Hence $\overrightarrow{C}$  makes an angle of ${180}^0$  with Z- axis
