Answer:
13 sides.
Step-by-step explanation:
(n - 2) = 1980 / 180 = 11.
n = 13
When the sum of the interior angles is 1980 degrees, the convex polygon will have 13 sides.
i hope this helps and is right! p.s. i really need brainliest :)
To find the length of the diagonals, Troy should use the Pythagorean Theorem. The diagonal is going to be the hypotenuse of the triangle (the side directly across from the 90 degree angle).
a^2 + b^2 = c^2
6^2 + 10 ^2 = c^2
136 = c^2; find the square root of 136
c = 11.66 feet
Troy's diagonals are approximately 11.66 feet.
Answer:
A total of 387 centimeters of ribbon are used.
Step-by-step explanation:
We already know that two out of three pieces of ribbon are 1.25 meters.
The third piece of ribbon is 120 millimeters (mm) longer.
1 millimeters = 0.001 meters
120 x 0.001 = 0.12
That means that the third piece of ribbon is 0.12 meters longer than the first two. The length of the third ribbon is 1.25 m + 0.12 m = 1.37 m
In order to find the total number of meters of ribbon used, we need to do addition.
1.25 m + 1.25 m + 1.37 m = 3.87 m
But, the question is asking us the number of centimeters of ribbon that are used.
1 m = 100 cm
3.87 x 100 = 387 cm
Therefore, a total of 387 centimeters of ribbon are used.
Hope this helps! Have a blessed day! :)
Answer:
answer is 90
Explanation:
Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.
So the product of other 3 factors should be greater than 16 and less than 20.
And we can have it from 18 only. Hence the number is 90.
The numbers between 80 and 100 having factor 5 are
<span>80,85,90,95,100</span>
<span>16=<span>24</span></span>
<span>17=17</span>
<span>18=2×3×3</span>
<span>19=19</span>
<span>20=<span>22</span>×5</span>
<span>90=2×<span>32</span>×<span>5</span></span>
