Answer:
1/2
Step-by-step explanation:
Because the solid triangle results in a smaller dashed triangle after the dilation, its scale factor will be a fraction. The length of the top side is 2 on the dashed triangle. It corresponds to the top side of the solid triangle which is 4.
2/4 = 1/2
The scale factor is 1/2 the size.
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!! :)
