Answer:

since the sum of interior angles of hexagon is 720 °

you add the known angles

ie 115 +90+145+160

you get 510

subtract it from 720

you get 210

divide 210 by 3

you get 70

Answer:

∠ CDE = 140°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

let ∠ DEF be x then ∠ CDE = 2x

sum the interior angles and equate to 720

160 + 90 + 145 + 115 + 2x + x = 720 , that is

510 + 3x = 720 ( subtract 510 from both sides )

3x = 210 ( divide both sides by 3 )

x = 70

Then

∠ CDE = 2x = 2 × 70 = 140°

What is the smallest degree of rotation that will map a regular 18 gon on to itself
natali 33 [55]

Answer:

  20°

Step-by-step explanation:

Rotating the figure through an angle equal to the central angle of one "sector" will do the required mapping. That is 360°/18 = 20°.

Which inequality is equivalent to I x-4 I <9
Leni [432]

(B) –9 < x – 4 < 9 inequality is equivalent to Ix-4I <9.

<h3>What is inequality?</h3>
  • Inequality is a statement of an order relationship between two numbers or algebraic expressions (greater than, greater than, or equal to, less than, or less than or equal to).
  • Inequality is defined as a difference in size, amount, quality, social position, or another factor.
  • Inequality occurs when you have ten of something and someone else has none.
  • (mathematics) A statement stating that one quantity is less than (greater than) another.

So, Ix-4I <9:

  • |x-4|<9 ⇒ -9 < x-4 < 9
  • -5 < x < 13

Therefore, (B) –9 < x – 4 < 9 inequality is equivalent.

Prove: △VWZ ≅ △YWZ
chubhunter [2.5K]

Answer:


Step-by-step explanation:

Statements                          Reasons

----------------------------------------------------------------

1. ∠V ≅ ∠Y                        Given

2. WZ bisects ∠VWY          Given

3. ∠VWZ ≅ ∠YWZ            Definition of Angle Bisector (2)

4. WZ ≅ WZ                         Reflexive Property

5. ΔVWZ ≅ ΔYWZ               AAS Theorem (1,3,4)

**In case you didn't know the definitions**

Angle Bisector - A line, segment or ray that divides an angle into two congruent angles

Reflexive Property - X = X

AAS Postulate -  If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangle's are congruent
