Answer:
51 degrees
Step-by-step explanation:
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!! :)
how would I know you can find your in if you read
Let:
Where:
k = scale factor
IW = 12
I'W'= 8
so, solving for k:
