Formula for number of sides, n = 360 / e
Where e is the exterior angle for the number of sides.
e = 21.2°
Number of sides for the regular polygon, n = 360° / 21.2°
n ≈ 16.98
The number of sides is approximately 16.98 sides..Does that make sense?
It does not. In fact, the exterior angle of a regular polygon has to be wholly divisible into 360°.
In the case 21.2° can't clearly be the exterior angle, the question is wrongly set.
The exterior can be say 20°.
Answer:38
Step-by-step explanation:
triangle=3*1=3
decagon=10*1=10
pentagon=5*5=25
3+10+25=38
Hello there!
Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.
Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25
So if:
48 feet ......> 12 inches
x feet ........> 0.25 inches
Cross multiply
12 * x = 0.25 * 48
12x = 12
Divide both sides by 12
12x/12 = 12/12
x = 1
The correct answer is option D, 1 foot
I hope this helps! Please let me know if you have any question.
Thanks!
