Would assume the Polygon is an 18 sided regular polygon.
Exterior angle for regular polygon = 360/n (Sum of angles of exterior angles = 360°)
where n = number of sides.
Exterior angle = 360 / 18 = 20
Exterior angle = 20°
Sum of exterior angle + Interior angle = 180° (Both angles are on a straight line, so the sum is 180°)
Interior angle = 180° - 20°
Interior angle = <span>160°

Answer:
1/4:1/5
Step-by-step explanation:
Remember you can do anything to an equation as long as you do it to both sides
a=age
500 reduced by 2 times a is equal to 388
500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56
you are 56
Jason earns 680$ in 40 hours.
Step-by-step explanation:
- Property used to solve this problem is <em>Algebra.</em>
- Jason earns <em>17$</em> which is fixed earning irrelevant of hours.
- hours is variable which means <em>n</em>.
- how much will he earn = 17 * number of hours (n).
- For n = 1, amount of money he would earn = 17 *1 = 17$
- For n =2, amount of money he would earn = 17 *2 = 34$
- For n = 3, amount of money he would earn = 17*3 = 51$
- For n = 40, amount of money he would earn =17*40 = 680$
- Algebra is branch of mathematics which help in puzzles and many problems from day to day life.In Algebra letters stands numbers and there operations can be done in the numbers.
So basically, you have to find the decimal that equals 1/2 and the fraction that equals 0.48, but it has to be in simplest form. If you divide 1 by 2, you get 0.5, which would be the answer to 1/2=. For 0.48=, you would start by putting 48 over 100 because if you read the decimal aloud, it is 48 hundredths and 0.48 goes to the hundredths place. Then, you would begin to simplify 48/100. A common divisor for those 2 numbers is 2, but you could also use 4. I am going to use 4, so 48/100=12/25. Now that you have the fraction 12/25, look to see if there are any common factors. There are none, so 0.48=12/25.
Hope this helps!! :)
