Question

AB=AD and BC=DC.
y = [ ? ]
Enter

Answer 1

Answer:

y = 49°

Step-by-step explanation:

∠DBC = ∠CBD  {  BC = DC ; angles oppostie to the equal sides are equal}

∠DBC + ∠CBD +  ∠C = 180   {angle sum property of triangle}

   y + y +82     = 180

               2y = 180 - 82

                  y = 98/2 = 49
