Answer:
x = 8.9
Step-by-step explanation:
We can see in the problem that the diameter is 37.8.
Radius is 1/2 of the diameter.
d = 2r
So in this problem r = 37.8/2 or r = 18.9.
Then you can see that the given side of the triangle is 10.
Since we know that that line is also the radius since it goes from the edge of the circle to the center, we can just subtract 10 from 18.9 to get 8.9.
