Answer:

The answer to your question is: y = 80°

Step-by-step explanation:

The sum of the internal angles in a polygon is = 180°(n - 2)

                                                                            = 180° (6 - 2)

                                                                           = 180(4)

                                                                            = 720°

                   y° + y° + 2(2y -20) + 2(2y -20) = 720

                   2y° + 4(2y -20) = 720

                   2y° + 8y -80 = 720

                   10y = 720 + 80

                   10 y = 800

                   y = 800 / 10

                   y = 80°

                 2y - 20 = 2(80) -20 = 160 -20 = 140

                 

                 80° + 80° * 140 + 140 + 140 + 140 = 720°

Indicate the method you would use to prove the two 's . If no method applies, enter "none".
Andrei [34K]
Answer: ASA method must be applied to the given triangles to prove then congruent.


In two triangles, if two angles and their included side are congruent then the two triangles are said to be congruent .This method is known as Angle-Side -Angle postulate(ASA).
In the given triangles one side with their corresponding angles are equal. Therefore by ASA postulate they are congruent.
There we can see no other sides are given equal therefore all the other options cannot be applied.

you are lucky I had this test yesterday and I have the answer is ASA my math teacher said it was fine

Without solving, explain how you can tell whether the solution to 0.5x = 10 is less than 1 or greater than 1 ​
NemiM [27]

Greater than 1 because left side is a fraction less than 1 and right side is a number greater than 1.

The left side being a fraction less than 1 could only mean that you have to multiply a number greater than 1 to the other side. And since the other side is a number greater already than 1 then multiplying the left side to the right side must result in a number greater than 1.
