Question

in the given figure AC = BC. find the value of x Give reason in support of your answer c130°​

Answer 1

Answer:

In ΔABC

AC=BC ----- (i)

∠BAC=∠ABC

∠BAC=180

∘

−125

∘

=55

∘

∠BAC=55

∘

(adjacent angles)

∠ABC=55

∘

(from (i))

In ΔABC

55

∘

+55

∘

+x

∘

=180

∘

x=70

∘

y=125
