Question

please solve this its urgent ​

Answer 1

Answer:(d) 70 degrees

Answer 2

Answer:

AB=AC

⇒∠B=∠C (As angles opposite to equal sides are equal)

Let each be y

Now in △ABC by using angle sum proerty of triangle

∠A+∠B+∠C=180

∘

x+y+y=180

∘

⇒x+2y=180

∘

..............(i)

Also

∠ABC+125

∘

=180

∘

(Supplementary angles)

⇒y+125

∘

=180

∘

..........(ii)

Slolving (i) and (ii)

⇒x=70

∘

,y=55

∘
