Question

In a quadrilateral ABCD,∆A=150° and ∆B=∆C=∆D,find ∆B,∆C and ∆D​

Answer 1

Step-by-step explanation:

B = C = D = 70

hope it helps

Answer 2

Step-by-step explanation:

Angle A +B+C+D = 360

150 +angle B + angle B + angle B = 360

3angle B = 360 - 150

3angle B = 210

angle B = 210 /3

angle B = 70

angle b = c= d= 70
