Answer:

3. None of the above ; 4. Equiangular

Step-by-step explanation:

Question 3. Pentagon.

B is <em>wrong</em>. The polygon is not equiangular, because ∠A ≠ ∠E.

C is <em>wrong</em><em>.</em> The polygon is not regular, because it is neither equiangular nor equilateral.

D is correct, because the polygon is none of the above.

Question 4. Quadrilateral

A is <em>wrong</em>, because AB ≠ AD.

B is correct, because every angle is 90°.

C is <em>wrong</em>, because AB ≠ AD.

Consider triangle abc what is the value of y in the triangle
Yakvenalex [24]

Answer:

y = 50

Step-by-step explanation:

All triangle angles add up to 180 degrees.

To set this equation up, you need to add everything given in the triangle and set it equal to 180:

y + y + 80 = 180

<em><u>Add like terms:</u></em>

2y + 80 = 180

<u><em>Subtract 80 from both sides:</em></u>

2y + 80 = 180

     - 80   - 80

___________

2y = 100

<u><em>Divide both sides by 2:</em></u>

y = 50

<u><em>If you're unsure, you can plug in the 50 for y:</em></u>

y + y + 80 = 180

50 + 50 + 80 = 180

100 + 80 = 180

180 = 180
