Answer: A △ABC such that the bisectors of ∠ABC and ∠ACB meet at a point O.
To prove :
∠BOC=90
o

1
∠A
Step-by-step explanation: In △BOC,
∠1+∠2+∠BOC=180
o
In △ABC,
∠A+∠B+∠C=180
o
∠A+2(∠1)+2(∠2)=180
o

Four 1/4's = 1 pound
So 4 people would eat 1 pound.
15 people / 4 = 3.75 pounds of turkey is needed.
3.75 is written as 3 3/4 using fractions
Check: 3.75 / 15 = 0.25 = 1/4
C) find the least common denominators
18 : 24 = 18/24 = 3/4 <==
Answer:
