the values of k and t will be found as follows:
ΔXVU is an isosceles triangle, thus the value of t will be:
t+64+64=180
t+128=180
t=180-128
t=52°
also:
ΔUVW is an equilateral triangle, we not that equilateral triangles have equal angle sizes. Thus each angle will be:
k=180/3=60°
hence the answer is:
C] t=52° and k=60°
