Question

In
a quederi lateral ABCD
D is equal to 150•and angle a =b=c find a, b, c​

Answer 1

Answer:

70°

Step-by-step explanation:

Angle D=150°

Let Angle A=Angle B= Angle C =x

According to the question:-

Angle(A+B+C+D)=360° (Angle Sum Property of Quadrilateral)

x+x+x+150°=360°

3x=360°-150°

3x=210°

x=210°/3

x=70°

Ans. So, Angle A=Angle B=Angle C=70°

Hope it helps!
