Answer: 1800°

Step-by-step explanation: In this problem, we're given that a polygon has 12 sides and we're asked find the sum of the measures of its interior angles.

The formula for finding the sum of the measures of the interior angles of a polygon is 180 (n - 2) where <em>n</em> represents the number of sides.

So here, since our polygon has 12 sides, we can plug a 12 in for the <em>n</em> in our formula and we have 180 (12 - 2) which is our equation.

Simplifying inside the parentheses first, 12 - 2 is 10 so we have 180 (10) which is 1800.

So if a polygon has 12 sides, then the sum of the measures of its interior angles is 1800°.

constant of proportionality

k=xy

k=30

therefore x=30/y

if x=3 y=?

y=30/3

y= 10
