Answer:
Length of x ~ 10.5; Option B
Step-by-step explanation:
1. There are three radii present in this problem. Of that the diamter is supposedly 42.2 units. Given that the radii should be ⇒ 42.2 / 2 ⇒ 21.2 units
2. With that being said the 3rd radii contains parts x and 10.6. By radii congruency, the length of all radii should be the same, so this 3rd radii should = 21.2 units as well. If so, by the Partition Postulate 21.2 = x + 10.6
3. Through algebra let us solve for x:
21.2 = x + 10.6,
x = 21.2 - 10.6,
Answer ~ Length of x: 10.5
