ivolga24 [154]

Step-by-step explanation:

Let the angle near point A be A.

Let the angle near point B be B.

Let the angle near point C be C.

Let the external angle near point A be extA.

Let the external angle near point B be extB.

Let the external angle near point C be extC.

According to exterior angle property,exterior angle of an angle is the sum of other two angles.

So,

extA=B+C\\extB=A+C\\extC=A+B

According to angle sum property,the sum of angles in the triangle add to 180

extA+extB+extC=B+C+A+C+A+B=2(A+B+C)=2\times 180=360^{0}

N76 [4]

Answer:

12 fiction books.

Step-by-step explanation:

Let b represent number of non-fiction books.

We have been given that in the library at Lenape elementary school, there are 3/8 as many fiction books as there are nonfiction books. So number of fiction books would be \frac{3}{8}x.

We are also told that there are 44 books in school library. We can represent this information in an equation as:

x+\frac{3}{8}x=44

Let us solve for x.

\frac{8x}{8}+\frac{3}{8}x=44

\frac{8x+3x}{8}=44

\frac{11x}{8}=44

\frac{11x}{8}\cdot \frac{8}{11}=44\cdot\frac{8}{11}

x=4\cdot 8

x=32

Therefore, there are 32 non fiction books in the library.

Number of fiction books would be \frac{3}{8}x\Rightarrow \frac{3}{8}*32=3*4=12

Therefore, there are 12 fiction books in the library.
