Four interior angles of a 7 sided polygon are equal, and the others add up to 120 find the size of the equal angle?

195°

Step-by-step explanation:

The sum of interior angles can be found by using this formula

(n - 2)180

(7 - 5)180

5 * 180

900 = sum of interior angles

900 - 120 = 780

Now we divide it by 4

780 ÷ 4 = 195°

The equal angles is 195°

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
