Answer:
360 degrees
Step-by-step explanation:
Remember that triangles have a sum of 180 degrees, and that quadrilaterals have 360 degrees.
You can either use that part, or actually solve for it.
The equation for the sum of the interior angles is:
[which "n" is the number of sides]
So, if we add in the number of sides to the equation, it changes to:
, which equals to 360 degrees.
Answer:
Kindly check attached picture for sample space design
45 ways
Step-by-step explanation:
Number of qualified candidates to be chosen = 2
Number of candidates to be interviewed = 10
Combination formula :
nCr = n! / (n-r)! r!
10C2 = 10! ÷ (10 - 2)!2!
10C2 = 10*9 / 2 * 1
10C2 = 90/2
10C2 = 45 different samples
Our sample space will contain 45 different samples
