Answer:
x = 2, y = 6
Explanation:
Δ WXY is equilateral ( 3 congruent angles ), then the sides are equal
WY = WX , that is
y - 1 = 5 ( add 1 to both sides )
y = 6
Δ WYZ is isosceles ( 2 congruent base angles ) then the legs are congruent
YZ = WY , that is
x + 3 = 5 ( subtract 3 from both sides )
x = 2
