Question

In a quadrilateral ABCD, the angles A, B, C, and D are in the ratio 1:2:3:4. Find the measure of greatest angle of the quadrilateral. a 360 b) 720 c) 1089 d) 1440​

Answer 1

Answer:

a) 720

Step-by-step explanation:

this is the answer

Answer 2

Answer:

Greatest angle would be 144°

Step-by-step explanation:

Let the angles be x,2x,3x and 4x

the sum of all 4 angles of a quadrilateral is 360°

x+2x+3x+4x=360°

10x=360°

x=360/10

x=36°

The angles will be

36°,72°,108° and the greatest angle would be 144°
