can someone help me to solve this question. the questions is about to calculate the value of x . please help me thankyou​

Step-by-step explanation:

AC = AD So,  Δ ACD is as isosceles triangle.

∠ADC ≅∠ACD = 63°

In ΔACD ,

    63 + 63 + ∠DAC = 180   {Angle sum property of triangle}

            126 + ∠DAC = 180

                     ∠DAC = 180- 126

                     ∠DAC = 54°

In ΔABC,

90+ 37 + ∠CAB = 180

        127 + ∠CAB = 180

                 ∠CAB = 180 - 127

                 ∠CAB = 53

∠EAD + ∠DAC + ∠CAB = 180   {Straight line angles}

x + 54  + 53 = 180

        x + 107  = 180

                  x = 180 -107

x = 73°
