Three angles of a quadrilateral are equal and the fourth angle is equa

1.	Three angles of a quadrilateral are equal and the fourth angle is equal to 144° find each of the equal angles of the quadrilateral
Answer» SUM of angles of quadrilateral = 360° let the equal angles be X, the fourth ANGLE =144° x+x+x+144°=360°=3x+144°=360°= 3x=360°-144°=216° =3x=216° = x=216°/3=72° The 3 equal angles are 72° .

Three angles of a quadrilateral are equal and the fourth angle is equal to 144° find each of the equal angles of the quadrilateral

Answer»

SUM of angles of quadrilateral = 360°

let the equal angles be X, the fourth ANGLE =144°

x+x+x+144°=360°=3x+144°=360°=

3x=360°-144°=216°

=3x=216° = x=216°/3=72°

The 3 equal angles are 72° .
