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
