Answer:
-9
Step-by-step explanation:
Theorem of cosine:
a²=b²+c²-2bc(cos α) ⇒cos α=-(a²-b²-c²) / 2bc
In this case:
a=15 cm
b=10 cm
c=5 cm
cos α=-(15²-10²-5²) / 2*10*5
cos α=-100 / 100
cos α=-1
A=arc cos -1=180º This is impossible, because:
A+B+C=180º; then B=C=0º This is impossible for make a triangle (B>0 and C>0 if we want to make a triangle).
Therefore: it is not possible can make a triangle with side lengths of 5 cm, 10 cm and 15 cm.
Answer:
13.8
Step-by-step explanation:
CG is 1/3 of KG
so 41.4/3 is 13.8. that is median of CG
your answer will be 2 inch for the first piece 4 inch for the second piece 20 inch for the last piece
Answer:
34 cups
Step-by-step explanation:
just multiply the value in quarts by the conversion factor 4. So, 8.5 quarts times 4 is equal to 34 cups
