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.
The Volume of the box has to equal 64
because all the sides have to equal 12
and 12/3 = 4
The answer is C because the formula is 2 x pai x radius
Answer:
B
Step-by-step explanation:
Since G(x) =F(x-6)-3
So on the x-axis it will shift - 6 units so to the left and - 3 units on the y-axis then 3 units down.
