How do I solve for the measures of the the interior angles of a polygon

Step-by-step explanation:

To solve for the interior angles for a polygon,

subtract 2 from the number of sides then multiply with 180

i.e, (n-2)180

e.g, in the case of a triangle, (3-2)180 = 1*180 = 180

As for square, (4-2)180 = 2*180 = 360

Hope u understand.

For a party, you can spend no more than $ 20 on cakes. The egg cake cost is $ 4 and the cream cake cost is $ 2. Write the linear inequality that models the situation. Graph the inequality. Suppose that the number of egg cakes we buy is represented by x and the number of cream cakes we buy is represented by y.
