Question

three angle of a quadrilateral are equal . the fourth angle is twice one of the angle find the measure of each angle

Answer 1

144 72 72 72 will be its angle by equation x+x+x+2x=360

5x=360
x=72
2x=144

━━━━━━━━━━━━━━━━━━━
$\mathfrak{\blue{Solution.}}$We know that sum of the angle of a quadrilateral is equal to 360∘360∘

Given :

Three angles are equal

Let the equal angle be x

FOURTH ANGLE IS TWICE ONE OF THE ANGE

SO 

3X+2X=360

5X=360

X=72

SO THREE ANGLES ARE 72 AND FOURTH ANGLE IS 144
