(-28-32r-x+ 1)(x-2)
Reil [10]

Answer:

−25x+54−32rx+64r−x^2

Step-by-step explanation:

(−28−32r−x+1)(x−2)

Add −28 and 1 to get −27.

(−27−32r−x)(x−2)

Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.

−27x+54−32rx+64r−x^2+2x

Combine −27x and 2x to get −25x.

−25x+54−32rx+64r−x^2

Each regular polygon has radil and apothem as shown. Find the measure of each numbered angle. ​
ruslelena [56]

Answer:

∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°

Step-by-step explanation:

Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)

 ∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°
