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 :)
Answer:
Step-by-step explanation:
The spinner should land on whatever color 25% of the time.
25% of 20 = 25/100 * 20 = 500/100 = 5
So the correct answer is the number of times the spinner lands on a color 5 times. Only white does that. All the other colors either go above 5 or below it.
Answer:
x > 10
Step-by-step explanation:
x-3 > 7
Add 3 to each side
x-3+3 > 7+3
x > 10
Yep! You did it correct :)
Answer:
c = sqrt(106)
Step-by-step explanation:
Since this is aright triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 9^2 = c^2
25 +81 = c^2
106 = c^2
Taking the square root of each side
sqrt(106) = sqrt(c^2)
c = sqrt(106)
