​

Answer 1

Answer:

x+2x+3x+4x=360⁰

10x=360⁰

x=36⁰

2x=72⁰

3x=108⁰

4x=144⁰

Answer 2

Step-by-step explanation:

Four angles of a quadrilateral are in the ratio in 1:2:3:4

let the angles are x ,2x,3x,4x.

total area of four angles are 360°.

x+2x+3x+4x=360°.

10x=360°.

x=360°/10.

x=36.

the angles of four ratios are

36, 72, 108, 144.
