Question

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

Answer 1

180-(63+63)

=180-126

=54

180-(37+90)

180-127

53

180-(54+53)

=180-107

=73°

Answer 2

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°
