angles.​

Answer 1

Answer:

I think it helps you

Step-by-step explanation:

as we know that,

a + b + c + d =360

a = 180

given,

b = c= d

so, a + 3b =360

180 + 3b =360

3b = 360-180

3b = 180

b = 60

hence we know that,

b = c = d

so, c = 60

d = 60

Answer 2

Answer:

since guadrilateral have 360 degree

so 360-180=180

means three angle is of 60 degree each
