Question

three angels of a quadrilateral are in the ratio 4:5:3.the difference of the least and the greatest of these angles is 42°.find all the four angles of the quadrilateral

Answer 1

let 4x+5x+3x = 42
12x=42
x=42 divided 12
x= 3.5
four angle of quatileteral is 3.5

Answer 2

Answer:

84,63,105,108

Step-by-step explanation:

Let the common ratio be x

therefore it will become 4x 5x 3x

5x-3x=42

therefore x=21

therefore the angles are

4x21=84

3x21=63

5x21=105

the fourth angle =360-(84+105+63)=108
