Hey there!

10 + 9 * (-3) (2) - (-1 + 8)

9(-3) = -27

10 + (-27)(2) - (-1 + 8)

-27(2) = -54

10 - 54 - (-1 + 8)

10 - 54 = -44

-44 - (-1 + 8)

-1 + 8 = 7

-44 - 7 = -51

Thus your answer answer is: -51 ☑️

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

$\sf Formula: \\\\\sin 2 \theta = 2 \sin \theta \cos \theta$

$\text {\sf \Large Solution :}$

$\cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta }{\sin 2 \theta } = \\\\\ \cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta}{2\sin \theta\cdot \cos \theta} =\boxed{\cos 2 \theta +\dfrac{1}{2} }$
