Answer 1

Step-by-step explanation:

Hack driver was Oliver Lutkins himself. He fooled people and never portrayed his real identity in front of the strangers. He was a dishonest person who played a lot of poker and was good at deceiving people. He owed money to many people, but he never paid anybody a cent.

Answer 2

Answer:

$\sin \: \alpha \: - \: \frac{cot \: \alpha }{2 \: tan \: \alpha } \\ \\ = sin \: \alpha \: - \: \frac{1}{2 \: {tan}^{2} \alpha } \\ \\ = sin \: \alpha \: - \: \frac{ {cos}^{2} \alpha }{2 \: {sin}^{2} \alpha } \\ \\ = \frac{(2 \: {tan}^{2} \alpha \: \times \: sin \: \alpha ) - 1 }{2 \: {tan}^{2} \alpha }$
