For this, find the value of X for this parallelogram!! Thank you :)

True [87]

Answer:

$\huge\boxed{\sf x = 12 }$

Step-by-step explanation:

Opposite sides and angles of a parallelogram are equal.

So,

3x - 1 = 35

Add 1 to both sides

3x = 35 + 1

3x = 36

Divide 3 to both sides

x = 36 / 3

x = 12

$\rule[225]{225}{2}$

Hope this helped!

Answer:

Step-by-step explanation:

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

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

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

V * v = v^2
v * -8 = -8v
8 * v = 8v
8 * -8 = -64

v^2 - 8v + 8v - 64
v^2 - 64
