You need this key result: in any polygon, the sum of the interior angles is

where
is the number of sides of the polygon.
Your polygon has seven sides, and the measures of all angles are given. So, we can write

Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.
We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:

and we can solve this equation for
by dividing both sides by 30:

Finally, the required angles is 
Answer:
17500
Step-by-step explanation:
you just multiply it by 35 if it is pennies but you have to tell me if it is dimes or whatever
I’m pretty sure that’s probably a nickel
Just move the decimal point 2 spaces to the left if you want it in the hundredth place. <span>.900 is the answer.</span>
