Answer 2

$\huge \mathfrak \red{answer}$

In quadrilateral ABCD <D = 150°

Let Angle A,B,C = x,x,x (As angles are equal)

x+x+x+150° = 360°

-> 3x+150° =360°

-> 3x = 360°-150°

-> 3x = 210°

-> x = 70°

Therefore, The angle A = 70°,Angle B = 70°,Angle C =70°,Angle D =150

Rechecking,

Angle A + angle b +angle c +angle d = 360°

70+70+70+150 = 360°

Hence verified!
