The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

<h3>What is the measure of the missing interior angle in a heptagon?</h3>

Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:

θ = (n - 2) · 180°, where n is the number of sides of the polygon. (1)

If we know that n = 7, then sum of the internal angles in the heptagon is:

θ = (7 - 2) · 180°

θ = 900°

And the measure of the final interior angle is found by subtraction:

θ₇ = 900° - 776°

θ₇ = 124°

The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

Sari is factoring the polynomial 2x2 5x 3. if one factor is (x 1), what is the other factor? 2x−3 2x 3 3x−2 3x 2

asambeis [7]

The other factor of the polynomial which Sari is factoring and found that the one factor of this equation is (x+1) is (2x+3).

<h3>What is a factor of polynomial?</h3>

The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.

The polynomial which Sari is factoring is,

$2x^2 +5x+ 3$

One factor of this equation is

$(x +1)$

Factor the given polynomial using the split the middle term method,

$2x^2 +5x+ 3\\2x^2 +2x+3x+ 3\\2x(x+1)+3(x+1)\\(x+1)(2x+3)$

Thus, the other factor of the polynomial which Sari is factoring and found that the one factor of this equation is (x+1) is (2x+3).
