If each interior angle of a regular polygon measures 180° how many sides does it have
Ne4ueva [31]

Answer:

This is impossible.

Step-by-step explanation:

The interior angle of a regular polygon is equal to

\frac{180(n   -  2)}{n}

where n is the number of sides.

Setting this equal to 180°,

\frac{180(n   -  2)}{n}  = 180 \\  \\  \frac{n - 2}{n}  = 1 \\  \\ n = n - 2 \\  \\ 0 =  - 2

which is false.

Solve for each variable.<br><br> 4. 8(2x - 1) - 5x = 102
zheka24 [161]

Solving for the variable of x in the equation, the value of x is: 10.

<h3>How to Solve for a Variable?</h3>

Given the equation, 8(2x - 1) - 5x = 102, to solve for the variable, x, we need to isolate "x".

8(2x - 1) - 5x = 102

Open the bracket

16x - 8 - 5x = 102

Combine like terms

16x - 5x - 8 = 102

11x - 8 = 102

Add 8 to both sides of the equation

11x - 8 + 8 = 102 + 8

11x = 110

Divide both sides by 11

11x/11 = 110/11

x = 10

Therefore, solving for the variable of x in the equation, the value of x is: 10.
