What is the measure of each interior angle does a polygon have if the sum of its interior angles is 1800°?

Answers

$\underset{in~degrees}{\textit{Sum of All Interior Angles}}\n\n S = 180(n-2) ~~ \begin{cases} n=\stackrel{number~of}{sides}\n[-0.5em] \hrulefill\n S=1800 \end{cases}\implies 1800=180(n-2)\implies \cfrac{1800}{180}=n-2 \n\n\n 10=n-2\implies 12=n \n\n[-0.35em] ~\dotfill$

$\underset{in~degrees}{\textit{Sum of All Interior Angles}}\n\n n\theta = 180(n-2) ~~ \begin{cases} n=\stackrel{number~of}{sides}\n \theta = \stackrel{degrees}{angle}\n[-0.5em] \hrulefill\n n=12 \end{cases}\implies 12\theta =180(12-2) \n\n\n 12\theta =1800\implies \theta =\cfrac{1800}{12}\implies \boxed{\theta =150^o}$

Is -1.5 greater or less than 1.3

Answers

The number - 1.5 is less than the number 1.3.

Used the concept of a number system that states,

A writing system used to express numbers is known as a number system. It is the mathematical notation used to consistently express the numbers in a particular set using digits or other symbols.

Given that,

The numbers are - 1.5 and 1.3

Since the negative number is always greater than the positive number.

So, we get;

- 1.5 < 1.3

As the number - 1.5 is negative and 1.3 is a positive number.

Therefore, - 1.5 < 1.3

Can both number be negative? if yes give an example

Answers

yes they can.
for example if you have - 7 + - 8=- 15 the rule for adding/subtracting is that when you have two negative you add and keep the negative sign. When you multiply/divide the two negative makes the answer become positive for example - 5 × - 7 = 35 or when you divide - 6 ÷ - 3 = 2.

Is 52L greater than 5,200mL?

Answers

1L = 1,000mL

therfore

52L = 52 × 1,000mL = 52,000 mL

52L = 52,000mL !!!!

5200mL → 520 cL → 52dL → 5.2L

Example:

If

1L ------ 1000mL
x -------- 5200mL

1000x = 5200
$x = (5200)/(1000)$
x = 5,2

Therefore:
52L > 5200mL or 5.2L (True)
