Question

find x and y pls find the answer​

Answer 1

Answer:

In ∆ ABC,

AB = AC [ so ∆ ABC is an isoceles triangle ]

< ABC = < ACB [ angles opposite to equal sides are equal ]

x = 40 °

In ∆ ABC,

x + y + 40 = 180 [ angle sum property]

y +40 +40 =180

y +80 = 180

= > y = 180-80 = > 100 °

Answer 2

Answer:

x=40

y=100

Step-by-step explanation:

As AB and BC are equal,(i.e. same length) hence the angles will also be equal.

So, x=40

And A+B+C=180

THEREFORE, A=180-B+C

A=180-80

A=100
