Question

the angles of a quadrilateral are in the raito 2: 4: 5: 7 find the angles​

Answer 1

Answer:

Step-by-step explanation:

The sum of all side of quadrilateral is 360°

The ratio of four sides of quadrilateral are 2:4:5:7

lets,four sides be 2x°,4x°,5x°,7x°

2x°+4x°+5x°+7x°=360°

18x°=360°

x°=360°/18

x°=20

that mean x°=20°.so,sides are:

1. 2x=2*20=40°
2. 4x=4*20=80°
3. 5x=5*20=100°
4. 7x=7*20=140°
