Aa criterion : if two corresponding angles of two triangles are congruent then the two triangles are similar

1 answer:

7 0

The angle-angle-angle postulate states that if two corresponding angles of two triangles are the same, the triangles are similar.
This is simply because the triangle's sides are not known but they are at the same angle to one another so the triangles must be similar.

Answer: 29

Step-by-step explanation:

Let S denotes the total number of people surveyed, A denotes the event of having dog , B denotes the event of having cats and C denotes the event of having fish.

Given : n(S)=50 ;n(A)=11 ; n(B) =13 and n(C)=6

Also, n(A∩B)=5 ; n(A∩C) = 2 and n(B∩C)=3 and n(A∩B∩C)=1

We know that,

$n(A\cup B\cup C)=n(A)+n(B)+n(C)-n(A \cap B)-n(A \cap C)-n(B \cap C)-n(A \cap B\cap C)\\\\=11+13+6-5-2-3+1=21$
