Question

hey guyz plss solve this​

Answer 1

Answer:

Given :– (i)Angle ABD = 125°

(ii) AB = AC

To find :– x

Solution :– ABD + ABC = 180° ( Linear pair)

125 + ABC = 180

ABC = 180 - 125

ABC = 55°

So, AB = AC ( Given)

So that Angle B = Angle C (Given)

Angle B = 55°

Angle C = 55°

Now, In triangle ABC,

ABC + ACB + x = 180° ( Angle sum property)

55° + 55° + x = 180°

110 + x = 180°

x = 70°
