Question

Angle da quadrilateral are in the
ratio 3:55:7. Find all in the angles
of the quadrilateral in degree
54,90,90,126​

Answer 1

first angle 3x

second angle 5x

third angle 5x

fourth angle 7x

total angle of a quadrilateral=360°

=3x+5x+5x+7x=360°

=20x= 360°

=x=360÷20

=18

3x=3×18= 54°

5x=5×18=90°

5x=5×18=90°

7x=7×18=126°

for check: 54°+90°+90°+126°=360°
