So it is an isosceles triangle that means that the bottom two angles are equal...
so 
40 = 5x 
divide both sides by 5 and you get 8

now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40

You are correct!!! :)

What related number sentence shows the commutative property of addition? 3+9=12
viva [34]
Easy all you have to do is do 3 + 9 equals 20 which we all know that because we're in high school haha anyways back to what you do 3 + 9 which equals 12 we do we have to flip it around so if you sent it around it will be 12 equals 9 + 3 no I just read it so it would be 12 plus 9 which equals 3 which we know that so you have to flip the device which is going to eat with 3 or 12 - 9 which is going to eat you 3 that's what I'm going to put with that

When you write a two column proof, the first thing in the reason column is always.....
Artemon [7]

The first thing in the reason column of a two colum proof is always GIVEN as it always coincide with an established fact which has been stated in the question to be worked on.

Two colum proofs involves using a tabulated format in establishing a conjecture.

Statements or facts are written on one side and the reason why the statement is true is stated in the reason column which is on the opposite side.

Starting a two column proof usually involve stating the the assumptions which are given about the shape or geometry.

Since each statement made requires a reason, then the reason behind the first statement which is based on what is stated in the question is written as GIVEN.

THEREFORE, after the statement given in the question has been established, then other reasons such as distributive, Commutative and other reasons may be used to proof one's solution statement.
