Question

one angle of angle of quadrilateral is 1800 and the remain 3 angles are equal. find the three equal angles​

Answer 1

so how??????? ..........

Answer 2

Firstly angle are not 1800 its 180 inly

Let the first angle =x

Let the second angle =x

Let the third angle =x

And angle 4=180

We know that the 1=2=3

3x

As we know the sum of all angles in quadrilateral are 360

3x+180=360

3x=360-180

3x=180

X=180/3

X=60
