just olya [345]
If we have a kite ABCD where AB = CD and DC = CA.
Let E be a midpoint between BC
Since triangle ABC is an isosceles triangle, ray BE bisects angle ABC and is perpendicular to AC.
So, angle ABE = CBE.
<span>Since also triangle CDA is isosceles, line DE is perpendicular to AC for the same reason. Therefore, AC is perpendicular to BD.</span>

sammy [17]

Answer:

The total number of ways to select 9 women and 4 men for the committee is 50,050.

Step-by-step explanation:

The club has 13 female members and 8 male members.

The committee to be formed must have 9 female members and 4 male members.

The possible number of ways to select 9 female from 13 females is:

n(F)={13\choose 9}=\frac{13!}{9!(13-9)!}=715

The possible number of ways to select 4 male from 8 males is:

n(M)={8\choose 4}=\frac{8!}{4!(8-4)!}=70

Compute the possible total number of ways to select 9 women and 4 men for the committee as follows:

Total number of ways to select 9 women and 4 men = n (F) × n (M)

                                                                                       =715\times70\\=50050

Thus, the total number of ways to select 9 women and 4 men for the committee is 50,050.
