Let's see what we can fill in here.
<ACE = 130
180 - 50 = 130
Now that we have two sides and an included angle, we can use the Law of Cosines.
Law of Cosines: c^2 = a^2 + b^2 - 2ab(cos(C))
Let's plug in what we know and solve!
c^2 = 40^2 + 38^2 - 2(40)(38)(cos(130))
R = 70.69706
Hope this helps!! :)
Find the slope: m=(6-8)/[5-(-1)]=-1/3
y=-1/3 x+b
find b: 8=-1/3 *(-1)+b =>b=23/3
so the equation is f(x)= -1/3 x + 23/3
Volume of a cube is side^3
therefor
v=27
27=side^3
what^3=27?
factor 27
27=3 times 3 times 3=3^3
27=side^3
3^3=side^3
cube roo bth sides
3=side
3 cm is on side
area=side^2
area=3^2
area=9 cm^2
Third side must be greater than (12 -7) or 5 and less than (12 + 7) or 19
So, third side could be A C E or F
