Answer:
<em>Darragh's coin has lost 0.163 g mass. </em>
Step-by-step explanation:
Mass of Darragh's coin is 13.551 g and mass of an uncirculated coin is 13.714 g.
For finding the loss of mass, we just need to <u>subtract the mass of Darragh's coin from the mass of the uncirculated coin</u>.
So, the loss of mass for Darragh's coin will be:
,k
n
The m∠ U is 72°.
Given:
To find :
Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as
Here we have n = 5 on substituting the values we get
Therefore,
m∠ U is 72°.
that's all about my answer
