Answer:
Is there any other numbers in that equation? I'm sorta confused. ;)
Step-by-step explanation:
I'm assuming the question is referring to a regular pentagon where all the sides and angles are equal, because otherwise, I would need more information (such as lengths of sides, meausures of angle, diagram, etc) to be able to solve this.
180(n-2)
n = 5 because a pentagon has 5 sides
5 - 2 = 3
180 * 3 = 540
divide 540 by 5 (again, because a pentagon has 5 sides)
540 ÷ 5 = 108
The sum of all the interior angles together is 540 degrees, and the measure of just one of them is 108 degrees
All you have to do is put 14 over 120 and divide. So 14/120 will become 0.11666666666 in decimal form. To round to the nearest thousandth, just count 3 places from the decimal point and look at the number to the right. If it is higher than 5, add one the 3rd number from the decimal, but if it is not, then just keep it the same. So, in this case it would be 0.117
Answer:
9
Step-by-step explanation:
She bet 9 each time, you can find this by doing 27 ÷ 3 :)
Answer:
D)
Step-by-step explanation:
Turn the smaller triangle. You will get similar triangle of 3/(altitude)=(altitude)/9. This means the altitude is 3sqrt3. Now just use the Pythagorean Theorem and get 27+81 or 108. Take the square root of this and you get 6sqrt3 or D).
