So we know that x+y+<1(the one that is not labeled or doesn't have a number)=180 degrees.
We also know that x+y= 98 degrees.
<1 and 98 degrees are supplementary. so <1=82 degrees.
We know that the triangle is isosceles so y=82 degrees as well.
We also know that a traingle =180 degrees so x=16 degrees
