Question

in a quadrilateral ABCD ,angle D is equal to 150° and angle A=angle B = angle C. find angle A ,B and C​

Answer 1

Answer:

D = 150 °

Let the angles a , b and c be x ( A = B= C)

A + B + C + D = 360 °

x + x + x + 150 ° = 360 °

3x + 150 ° = 360 °

3x = 360 ° - 150 °

3x = 210 °

x = 210 ° / 3

x = 70 °

So , A = B = C = 70 °

I hoppe it helps ^_^
