the measure of each of the angle of the
quadrilateral​

Answer 1

Answer:

property of quadrilateral

property of quadrilateralsum of all angles is 360°

____________________________

let the two angles be 3x° and 5x°

72°+56°+3x°+5x°= 360°

8x°+128°= 360°

8x°=360-128

8x°= 232

x = 29

5x°=5 x 29=145°

3x°=3 x 29= 87°
