Answer:

A central angle has the same measure as its arc.

Step-by-step explanation:

We have been given a statement and we are supposed to fill in the given blank.

Statement: A angle has the same measure as its arc.

Since we know that in a circle the measure of inscribed angle is half the measure of its subtended arc and the measure of central angle equals to the measure of its subtended arc.

Therefore, the missing word from our given statement is "central".

Simplify ( 1/2A + 1/2B )^2

zysi [14]

Notice that both A and B are multiplied by (1/2).

Thus, the given expression can be re-written as [(1/2)(A+B)]^2.

Square the (1/2) and the (A+B) separately, and then multiply together the resulting squares:

(1/4)(A^2 + 2AB + B^2)

A survey was given to 339 people asking whether people like dogs and/or cats.

liubo4ka [24]

Answer:

80.

Step-by-step explanation:

Let $C$ be the set of people who like cats and $D$ the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the $(C$ ∩ $(D$ , you have n $(C$ ∩ $(D$ = n(C) + n(D) - $(C$ ∪ $.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C$ ∩ $(D$ $= 190 +141 -251 = 80$
