Answer:
70.52 degrees
Step-by-step explanation:
To find the angles, we must first find the lengths of each side of the triangle. Adding up the respective radii, we can see that
XY = 5+4 = 9 CM
XZ = 6+5 = 11 CM
ZY = 4+6 = 10 CM
Now we can apply the cosine rule

We need to rearrange the rule to solve for x, our missing angle

solving for our unknown angle:


Therefore angle YXZ is 70.52 degrees
Answer:
55
Step-by-step explanation:
If 1 gift takes 1/5 an hour, then 5 gifts would take one hour. So if she makes 5 gifts an hour for 11 hours she would make 55 gifts in 11 hours.
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %
