Question

Y’all need to solve this to see if I’m correct… I got the answer of 144 is it correct? If not what’s the real answer..

Answer 1

Answer is 144 yeah you're good

Explanation:

To find any sum of the interior angles for any regular polygon, you would use the equation (n - 2) * 180 [With n being the number of sides the polygon has]

Since the decagon has 10 sides n would be equal to 10, now plug it into this equation

`= (10 - 2) * 180\\= 8 * 180\\= 1440`

So now we know the sum of the interior angles of the decagon is 1440, now if you were to find out the measurement of an interior angle for this decagon you would divide the sum of the interior angles by the amount of sides of the polygon.

In which case, the decagon has ten sides so...

`= (1440)/(10) \\= 144`
