Central angle of a regular polygon:
Ф = 360° : n.
If n=12: Ф = 360° : 12 = 30°
At the angle of rotation Ф = 30° the image of the polygon will coincide with the preimage.
Multiply 12 and 12 which is 144 and then add the exponents which would be 10 and so your answer would be 144*10
Answer:
62.5% increase
Step-by-step explanation:
First step : find the difference between two numbers, in this case, it's 1300000 - 800000 = 500000.
Second Step: Take the difference, 500000, and divide by the original number: 500000/800000 = 0.625.
Last, multiply the number above by 100: 0.625*100 = 62.5%. You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 62.5%.

Answer is 16
8 (6 1/4 x 3.2 - 18)
8 ( 6x4+1) = 25/4
8 (25/4 x 3.2 - 18)
8 (25/4 x 3.2) = 80/4 = 20
8 (20 - 18) = 2
8 x 2 = 16
