68 + a = 180
a = 180 - 68
a = 112
b = 2(112) - 104
b = 224 - 104
b = 120

Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
The value of the unknown number k with the given percentage is 192.31.
The given parameters;
- <em>percentage of the unknown number = 65%</em>
- <em>result obtained from 65% of k = 125</em>
The original value of the unknown number "k" is calculated by setting up a linear equation as follows;

Thus, from the result above we can conclude that the value of the unknown number "k" is 192.31.
