the sum of the measures of the interior angels of a convex polygon is 3240 classify the polygon by the number of sides
1 answer:
Answer:
20-gon
Step-by-step explanation:
First we start with the formula to find what the sum of angles will be if we know the number of sides.
S=(n-2)*180 where S is the sum of angles and n is the number of sides.
Normally you'd plug in n to find S, but you can do the opposite too.
3240=(n-2)*180

- 2 3/5 - 1 2/3
= -2 9/15 - 1 10/15
= (-2 9/15) + (- 1 10/15)
= -3 19/15
= -4 4/15
Answer is B
-4 4/15
The answer is 6.82
2 + 4 = 6
.05 + .77 = .82
6 + .82 = 6.82
Answer:
x=8
Step-by-step explanation:
solve the rational equation by combining expressions and isolating the variable x
Step-by-step explanation:
n(S) = 25
Assume that O : odd numbers and E : even numbers,
n(O) = 13
n(E) = 25-13 = 12
P(OO) = P(O) x P(O)
= 13/25 x 12/24
(because without replacing so the number of balls left decreases)
= 13/25 x 1/2
= 13/50
