Answer:
- triangles
- 180°
- triangles, 180°
Step-by-step explanation:
A diagonal divides a polygon into two parts. Drawing all of the diagonals from a given vertex to the other non-adjacent vertices will divide the polygon into triangles.
The angle sum theorem tells you the sum of triangle angles at any polygon vertex will be equal to the measure of the interior angle of the polygon at that vertex. Since we're concerned only with triangles created by drawing diagonals between non-adjacent polygon vertices, the sum of triangle angles will be the sum of polygon angles.
So, you can multiply the number of triangles by 180° to find the sum of interior angles of the polygon. (The number of triangles is two fewer than the number of polygon sides.)

Answer: 9/38</h3>
Reason:
There are 10 red cards out of 10+10 = 20 total.
10/20 = 1/2 is the probability of selecting a red card.
If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19
Multiply the two fractions mentioned to get the final answer.
(1/2)*(9/19) = (1*9)/(2*19) = 9/38
