Help me please thank you

x = 30°

A || B =>

=> 4x + 2x = 180°

6x = 180°

x = 180° : 6

x = 30°

Elena stole 9  bases.

Step-by-step explanation:

Using the give information, we will represent the number of bases that Natasha sold by the variable x and the number of Bases Elena stole by the variable y.  

If Natasha stole three fewer bases than twice the number Elena stole, the we can represent that by the equation   x = 2y - 3      

And it also says that Natasha stole 15 bases so we can also represent that by the equation   x= 15

x = 2y -3  

x= 15    

Now using both equations substitute the value for x in the second equation into the first equation and solve for y so find out the number of bases Elena stole.

15 = 2y - 3       Add 3 to both sides

+3          +3

18 = 2y              Divide both sides by 2

y = 9
