Question

find x and y.is triangle abc Isocelese?if so name its equal sides​

Answer 1

Answer:

In triangle ABC AND BC has produced to x

so.,

40 +y = 110 ( exterior angle )

y = 110-40

=70

and xBC is a straight line

so,

x + 110 = 180 ( linear pair)

x = 180-110 = 70

Answer 2

Step-by-step explanation:

x = 180°-110° [LINEAR PAIR]

x = 70°

In ∆ABC,

Angle A + Angle B + Angle C = 180°

40°+70°+ Angle C = 180°

Angle C = 180°-110° = 70°

x = 70°

y = 70°

Yes, the triangle is isosceles. The equal sides are AB & AC.
