5x + 32 = 4- 2x 
Add 2x to both sides to get 7x + 32 = 4
Subtract 32 from both sides to get 7x = -28
Divide both sides by 7 to get x = -4
Hope this helps :)

Hi there!

To solve this problem, we need to simplify.

5x + 32 = 4 - 2x
7x + 32 = 4
7x = -28

x = -4

Hope this helps!

Quadrilateral ABCD​ is inscribed in this circle.
Svetllana [295]

Answer:

132°

Step-by-step explanation:

Quadrilateral ABCD is inscribed in a circle,

So, it is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

\implies \: x \degree + (3x - 12) \degree = 180 \degree \\  \\ \implies \: (4x - 12) \degree = 180 \degree \\  \\  \implies \: 4x - 12  = 180  \\  \\ \implies \: 4x   = 180  + 12 \\  \\ \implies \: 4x   = 192 \\  \\ \implies \: x   =  \frac{192}{4}  \\  \\ \implies \: x   = 48\\\\

(3x-12)° = (3*48 - 12)° = (144 - 12)° = 132°

\implies \: m\angle B   = 132\degree\\\\

The sum of the interior angles of a convex n-sided polygon can be found using the formula:
Maksim231197 [3]

It is: 180(n-2)

For example, the sum of the interior angles of a triangle is 180 degrees.

The quadrilateral can be cut into two triangle so the sum of the interior angles of a quadrilateral is 180*2=180*(4-2)

The pentagon can be cut into three triangle so the sum of the interior angles of a pentagon is: 180*3=180*(5-2)

The hexagon  can be cut into four triangle so the sum of the interior angles of a hexagon is: 180*4=180*(6-2)
