Question

6. In the given figure, if AB - AC, then what is the value of x?​

Answer 1

125 + ∠ABC = 180    { Supplementary angles }

∠ABC = 180 - 125

∠ABC = 55

Now ,

∠ABC = ∠ ACB = 55  { Angles opposite to equal sides are equal }

∠ABC + ∠ACB + x = 180  { Angle sum property of Δ }

55 + 55 + x = 180

110 + x = 180

x = 180 - 110

x = 70
