Part A
This is an equilateral triangle since all sides are the same length (11). All equilateral triangles have 60 degree angles for each interior angle.
Answer: 60
=========================================================
Part B
The tickmarks tell us that WX and XY are the congruent sides, ie they are the same length. This means we have an isosceles triangle. The angles opposite the congruent sides are congruent angles.
angle W = angle Y = 35
From here, we use the idea that for any triangle the angles must always add to 180
W+X+Y = 180
35+X+35 = 180
X+70 = 180
X = 180-70
X = 110
Answer: 110
