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!!! :)

Hello from MrBillDoesMath!
Answer:
4x
Discussion:
(2x -y ) + (2x + y) = by the Associative property
(2x + 2x ) + ( -y + y ) =
4x
Thank you,
