Given : In Triangle ABC AB=AC,

∠A : ∠B = 4 : 3

To Find : value of  ∠C​

Solution:

In Triangle ABC,AB=AC,

∠B = ∠C    angles opposite to equal sides are equal )

Let say ∠A  = 4x

then ∠B = 3x   as   ∠A : ∠ B = 4 : 3

∠C   =  ∠B = 3x

∠A +  ∠B + ∠C = 180°

=> 4x + 3x + 3x = 180°

=> 10x = 180°

=> x = 18°

∠C   =   3x

=> ∠C   = 3(18) = 54°

Value of  ∠C = 54°
