Solve for the missing variables
x=?
y=?

x=70; y=55

Step-by-step explanation:

So with the triangle with x, you can tell that the triangle is an icoceles based on how 2 of it's sides are equal lengths.

And so, an icoseles traingle also has two of the same angles so you can say that

55+55+x=180

110+x=180

x=70

Now the triangle with y is also an isoceles, and you can see that there is a verticle angle pair.

So,

y+y+70=180

2y=110

y=55

and to double check,

55+55+70=180

110+70=180

180=180

Hope it helped!
