The sum of the angle measures of a polygon with s sides is 2340. find s.

Leviafan [203]

S=15

Whatever the number of sides of a polygon,

the sum of its exterior angles is always 360∘

Further, each pair of exterior angle and interior angle adds up to 180∘

Hence in a polygon with s sides (or angles),

the sum of all the interior and exterior angles would be 180∘×s

and sum of interior angles would be 180∘×n−360∘=180∘(s−2)

As sum of angles is 2340∘

Hence, 180(s−2)=2340 or s−2=2340180=13

and s=13+2=15 and polygon is a Pentadecagon.

i hope u understand :)

The answer is line X. I figured it out by graphing the four lines myself and when you graph line X, the slope is 3 and the y intercept is 5.

I hope this helps! Sorry it was late.

Three coins are dropped on a table.

Dominik [7]

Answer:

(a) S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

(b) $\frac{1}{8}$

(d) $(\frac{1}{2})^3 + \binom{3}{1} (\frac{1}{2})^3 = \frac{1}{8} + \frac{3}{8} = \frac{1}{2}$

(e) $1 - \frac{1}{2} = \frac{1}{2}$

(f) Yes, because $P(A \cap B) = 0$ . Therefore $P(A \cup B) = P(A) + P(B) = \frac{3}{8} + \frac{1}{2} = \frac{7}{8}$

(g) No, because $P(A \cap C) = \frac{3}{8}$ . Therefore $P(A \cup C) = P(A) + P(C) - P(A \cap C) = \frac{3}{8} + \frac{1}{2} - \frac{3}{8} = \frac{1}{2}$
