What is the sum of the measures of the interior angles of a pentagon and 10-gon (decagon)?
Please help right now! :(

the sum of the measures of the interior angles of a pentagon is 540 degrees and that of a decagon is 1440 degrees

Step-by-step explanation:

The formula for finding the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.

A Pentagon has 5 sides. This means that the sum of the angles in a heptagon is

180(5 - 2) = 180 × 3 = 540 degrees

A Decagon has 10 sides. This means that the sum of the angles in a heptagon is

180(10 - 2) = 180 × 8 = 1440 degrees

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
