Answer:
19/50
Step-by-step explanation:
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

so,

it equals 12.49 or 12.5 depending on rounding
I hope this helps!
Answer:
<u>Mean = 6.8</u>
Step-by-step explanation:
<u>Given data set :-</u>
{14, 7, 2, 8, 3}
<u>To find :-</u>
Mean
<u>Solving :-</u>
Take sum of given data and divide by number of data pieces.
=> 14 + 7 + 2 + 8 + 3 / 5
=> 34 / 5
=> 6.8
<u>Solution :-</u>
<u>Mean = 6.8</u>
