Expert Answer:

In the first triangle, the angles opposite to equal sides will be equal.
So, two angles will be yo
Using exterior angle property, we have
130o = yo + yo
130o = 2yo 
y = 65
 
In the second triangle, the angles opposite to equal sides will be equal.
So, two angles will be yo
Using exterior angle property, we have
100o = yo + yo
100o = 2yo 
y = 50
