is the answer to the prob.
Answer
Find out how many eighty fours are in 672.
To prove
Let us assume that the number of the 84 be x .
As given in the equation
Total values given in the question be 672.
Than the equation becomes
84 × x = 672
Simplify the above equation
84x = 672
x = 8
Therefore the Numbers of eighty fours in 672 is 8 .
The answer is 7.15 which is also equivalent to 7 15/20
Combine like terms:
2x - x + 3
x + 3
Once there is no more simplification to be done, your final answer remains which is the above equation.
The sum of interior and exterior angle is 180, thus<span>Interior angle =180−72=108 degrees </span>Let n be the number of sides of the polygon<span><span>(n−2)×180 / n = interior angle =108</span></span><span>72n = 360</span><span> n = 5 sides, hence this is a pentagon.
Sum of the interior angles = 108*5 = 540 degrees.</span>
