hey mate
here is your answer

i) ABC is a isosceles triangle
as,AB=BC
so, angle ABC= angle ABC

80°=x

ii) in ∆MNL
NL =ML
so,
angleMNL =angle NML
20°=angle MNL

angle NLM =180°-40°=140°
140°=b

4) ∆PQR is a isosceles triangle
x=180°-118°=62°

exterior angle is equal to sum of opposite interior angles

x=32°+y
62°-32°=y
30°=y

hope it helps
