Question

Three angles of the quadrilaterals are in the ratio 2:3:4. The sum of the least and the greatest of these three angles is equal to 180°. Find all the angles of the quadrilateral​

Answer 1

Answer:

Let 2:3:4:be x = 1equation

so , we know that

2x+3x+4x= 180

9x= 180

x=180/9

x= 20

put in equatuon 1 2×20=40

3×20=60

4×20=80

we know that

a+b+c+d= 360 so

40+60+80+d = 360

180+d= 360

d=360/180

d=180
