5) One angle of a quadrilateral is 180º and the remaining three angle

1.	5) One angle of a quadrilateral is 180º and the remaining three angles are equal. Find the threeangles.
Answer» 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

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
